== GUI and usability improvements ==
A number of aspects of the Sugar UI have been revamped to improve the user experience.


== Upgrading from previous releases ==
===Home view===
There are now three distinct view options:


For technical details and other upgrade options see [[olpc-update]] and [[Clean-install procedure]]. If you run into trouble, see [[Upgrade troubleshooting]], [[Support FAQ]] and [[Support]] to email our tech support volunteers.

Image:Home Ring View8.2.png|'''Home Ring view'''
Image:Home List View8.2.png|'''Home List view'''
</gallery>


=== If your XO is connected to the internet ===
;Freeform
This view shows only favorite activities. The activity icons can be positioned by dragging them around the screen.
;Ring
This view shows only favorite activities. The activities are kept neatly ordered within a ring surrounding the XO.
;List
This view shows every activity currently installed on the laptop, as well as other info about them such as their installation date and version number. The search field allows children to easily locate an activity in the list. Favorite activities can be specified here by starring them.


'''Note that this process may make some of your Activities and the Journal items that depend on them not work - make sure you have backed up any files you want to save!'''
;Launching activities


This process can take more than 30 minutes, much longer if you have a slow internet connection.
The Home view serves as a space for launching new activities. The Frame now contains the running activities which used to appear in Home. Clicking on an activity icon will launch it with a pulsing icon shown in the center until the activity starts. This feedback shows that the activity is starting and discourages users from launching many activities at once.

;Removing activities

[[Image:Removing Activities8.2.0.png|thumb|right|Activities can be individually erased to free up space for new Activity course material]]
By hovering over the activity icon it's possible to take other actions as well. For instance, one may easily add or remove it as a favorite activity, or remove the activity completely, uninstalling it permanently. To prevent accidental deletion, a confirmation step is required when deleting activities.

=== Frame ===
In the new Frame, the edges represent: places, people, devices, and objects. The Frame is accessed by putting the cursor in the corner or on the edge of the screen (see Frame control panel for setting these options) or by pressing the Frame key in the upper right of the keyboard. If the Frame is started by key stroke it must be removed by keystroke.

[[Image:Frame-01.jpeg|thumb|right|The Frame is accessible from anywhere]]

;1. Places
The top edge shows the "places" within the UI. The zoom level buttons appear here. The list of currently running activities also appear on the top edge of the frame; the active activity is highlighted. The Journal is always present here as a running activity.
;2. People
The right edge serves as an "active buddy list." Other XOs with whom the XO is collaborating appear on the right edge of the Frame.
;3. Devices
System status is in the bottom edge of the Frame. The battery level, network status (including the new mesh device, which allows one to switch channels), and speaker all appear here.
;4. Objects
The left edge of the Frame serves as a multi-item clipboard. The currently selected item will be pasted when the paste button (or shortcut) is invoked.

=== Journal ===
The 8.2 release includes an updated Journal The look is cleaner and some additional features have been added to make object management easier.

;'''List view'''

The list view still contains a list of all of the objects created on the laptop, ordered by date. Resuming an activity is as simple as clicking on the activity icon itself. There are a few enhancements to the Journal list as well:

;In-line renaming
It's now possible to rename entries directly within the list view, by clicking on the title text. A text field will appear to receive changes, which can be confirmed or canceled with enter and esc, respectively.
;Object palettes
The objects represented within the entries (specifically, activity and people icons) now have palettes attached to them. By hovering over their icons, it's possible to find out more information about them, such as the name of the person, and take actions on them, such as copying or deleting an entry. These changes make it possible to do more from the list, without having to constantly enter the detail view.
;Better feedback
The Journal now provides better feedback in edge cases, for instance when there are no search results returned for a query, to prevent confusion.

;'''Details view'''
By clicking on the details button (the little arrow) at the right of an entry, a child can view the details page for the entry. This includes a preview, editable description and tags, and other info about the entry. The toolbar at the top of the screen provides useful actions for launching, copying, or deleting the entry.

=== Graphical sugar control panel ===
Accessible from the pop-up menu of the XO icon in the [[home view]], the control panel currently provides a graphical interface for setting language, power, UI, date and other options. More detailed instructions can be found [[Sugar_Control_Panel#The_graphical_user_interface| here]].

== Automatic Software Updates ==
This release introduces an automatic updater to help you get the latest Activities. Activities are maintained separately from the core operating system. So newer activities may have become available since the software on your XO was installed. The software updater looks for the latest version of activities and offers to update them when new versions are available.

Note: it is especially important to update your Activities after upgrading from build 656 or earlier.

The Software Updater will prompt you to update immediately after you upgrade to release 8.2. You can also open it from the main Sugar Control Panel.

To use the Software Updater you must be connected to a network. The tool will check for existing activities on your XO and then check if there are newer versions available. You can then choose to update to the newer activities by selecting them and choosing 'Install now'.

You can also subscribe to different "Activity Groups" with interesting collections of activities, by clicking on the "Edit Activity Groups" expander in the control panel. The [[activity groups]] page on our wiki lists some interesting activity groups you can try.

A list of available activities is [[activities|here]].

For activity authors and developers, technical details can be found at the [[Software update]] page on our wiki.

== Backup and restore to school server ==
This feature will automatically backup an XO at least once a day to its registered school server. This feature is only relevant for school systems which have implemented the OLPC School Server. It is not available for home users.

To restore a previous backup from the XO, open the Browse activity, click on "Schoolserver", and choose the files which you wish to restore.

You must use XS version 0.4 ([[XS_Release_Notes|XS Release Notes]]) or later to take advantage of this feature.

*[[XS_Blueprints:Datastore_Simple_Backup_and_Restore|Detailed Documentation on Backup and Restore]]

== Longer battery life ==
The XO has several power saving modes.

'''Default Power Management''' <br>
With no checkboxes selected in the power save control panel the XO will save power in the following ways:<br>

* The XO screen will go blank if you do not touch the keyboard or touchpad for 20 minutes. When this happens, touching the keyboard or touchpad will wake up the display.

* If you close the lid or press the power button briefly then the XO will go in to suspend mode. In suspend mode the CPU stops running programs. The screen goes black. The wireless will continue operating if you are connected in a Mesh but it will shut down if you are connected to an access point. Awaken the machine by pressing the power button again, or by opening the lid.

'''Important note: the following functionality is not a supported feature yet. You may experience unexpected behavior after checking the Automatic Power Management or Extreme Power Management, but you can help us try it out and find issues.'''

'''Automatic Power Management''' <br>
If you select the Automatic Power Management check box in the Power panel under the Graphical sugar control panel, the XO also saves power in the following ways:<br>

* The screen dims and the XO goes in to "idle suspend mode" if you don't touch the keyboard or touchpad for one minute and the CPU is idle. In "idle suspend mode" the CPU will stop running programs, while leaving the display on (but dimmed).

* In "idle suspend" mode, if you touch the keyboard or touchpad, the XO screen will wake up from dimmed mode and the CPU will restart.

* When the XO enters "idle suspend" mode it powers down all USB ports including any USB to Ethernet connectors. Because not all devices can recover from this automatically, you may need to reconnect those external devices or reboot the XO to enable them again. As an exception to this guideline, USB storage devices ("USB sticks") do work correctly after a suspend and resume (but they should not be removed while the system is suspended).

If the laptop is in "idle suspend" mode when the lid is closed, the display will remain active. To fully suspend the laptop, the lid should be opened, and closed again, or the power button should be pressed before closing the lid.

'''Extreme Power Management''' <br>
If you select the Extreme Power Management check box in the Power panel under the Graphical sugar control panel, the XO saves power in the following ways:<br>

* The wireless radio is shut off immediately and for the duration that Extreme Power Management is activated.
No wireless networking is possible when in this mode.

For more detail on the intended design of power saving modes, see: <br>
http://wiki.laptop.org/go/Suspend_and_resume

== Languages and keyboards ==

== Fedora 9 ==
We've upgraded our base system to the [http://docs.fedoraproject.org/release-notes/f9/ Fedora 9] release from our partner, [http://redhat.com Red Hat]. The [http://docs.fedoraproject.org/release-notes/f9/ release notes] for Fedora 9 describe some of the improvements we've inherited, although builds for the XO do not include all the features of Fedora 9 by default.

= Upgrading from previous releases =

Be sure to read and carefully follow these instructions before you begin the upgrade process, and allocate enough time to do the full process before you begin.

'''During pre-release development, you will need a [[developer key]] in order to install an 8.2 [[OS Images|OS image]]. This key should be copied in the /security directory BEFORE the upgrading process.'''

'''Important Note: Please check with your deployment technical contacts before upgrading. Countries using the XO may have custom configurations which may require special actions to be taken before new releases can be installed.'''

The process described below is to upgrade the XO while it is connected to Internet, for other ways to upgrade, see the [[Upgrading_the_XO#Overview_of_Upgrading_Options | Upgrading the XO]].

Here are the steps to upgrade:
# Plug the XO into AC Power
# Connect XO to the internet
# Launch the update command
# Update activities

== Step 1: Plug the XO into AC Power ==
Upgrading could be a long process. For this reason, ensure first that your XO is connected to reliable AC Power. Be sure to have enough time to do the full process (about 1 hour).

== Step 2: Connect XO to the internet ==
During the upgrade process, your XO will download the new release. So you should ensure that the XO is connected to the internet before launching the upgrade. See [http://laptop.org/laptop/start/connecting.shtml Connecting Guide] or [[Wifi Connectivity]] for instructions. Use Browse activity to test your connection.

== Step 3: Launch the update command ==
Open the '''[[Terminal Activity]]''' [[Image:Activity-terminal.svg|35px]] or a console and type the following (press the Enter key after it):

sudo olpc-update ''{{:Friends in testing/current image}}'' <!-- reboot, verbose -->

If the update program successfully connects to the update server, some messages should display similar to this:


# Make sure your XO is plugged in, turned on, and [http://laptop.org/manual/XO_GiveMeTheInternet.html connected to the Internet] (you should be able to load http://laptop.org in the Browse Activity). If your XO is not connected to the internet, you will not be able to use this upgrade method.
# Open the Terminal Activity. [[Image:Activity-terminal.svg]] You can find it by going to the home view (press the 5th symbol from the left, top row), clicking on the little arrow at the bottom right of the screen, and then on the symbol that looks like this one.
# In the Terminal Activity, type <code>su -</code> (lowercase letter 's', lowercase letter 'u', a space, and a hyphen). Press Enter.
# At the <code>"-bash-3.2#"</code> prompt type <code>olpc-update 767</code>. Press Enter.
# You should see text that looks something like this (sometimes, in addition to the text below, you might get a message about irsync_pristine failing, and that "irsync_dirty" is being tried, this is normal):
<pre>

</pre>
6. At the end of the upgrade, you will either see the words "Installing update in...." or "Update Succeeded!" on the screen. If you see the words "I don't think you're connected to the internet." see the notes below. <br>
<br>
7. Wait for the prompt <code>"-bash-3.2#"</code> and type <code>reboot</code> then press Enter to restart your XO. You will probably hear the little XO tune 2 times, then it will say erasing and a countdown will appear. Finally it will reboot again, you will hear the tune for a third time. Now you are ready to go to step 8.<br>
<br>
8. After your XO reboots, the last step is to download the new versions of Activities. When the XO boots you will see a bar toward the top of the screen that says "Software Update" and the options being "Cancel", "Later" and "Check now". Before you choose "Check now" to update the activities, you must reconnect your XO to the internet. You may see the sign-in box appear in home view. If it does, and it lists your router, you can do it from there. If it doesn't appear or offers the wrong connection, go to the Neighborhood view and connect from there. Then go back to Home view and then click "Check now" (it's ok to leave the home view because when you go back the options should still be there). First the XO will check for any updates and then it asks if you'd like to install them. Click "Install selected" to install your newest versions of your activities. <br>


Congratulations, you've upgraded!
This process may take more than thirty minutes. When the process is complete, you need to [[reboot]].


'''Note:'''
'''Important Note: On the first reboot after upgrading, the XO will run slowly for about 1 minute. After that it will run normally.''' <trac>7356</trac>
* When upgrading from build 703 or 708 you will not see the Library (links to science, books, etc links on the left side) in the Browse home page. You can re-install the Library as follows:
** Open the Control Panel and go into Software update.
** After it checks for updates, go to <code>"Modify activity groups"</code> and click on the triangle.
** Beside <code>"Group URL"</code> type: <code> http://wiki.laptop.org/go/Activities/G1G1 </code> and click the <code>"Add"</code> button.
** Click <code>"Refresh"</code> and allow the XO to upload the new updates.
** Click on Install selected. Once it completes, reboot.
* If you can browse the Internet (see step 1 above) but the <tt>olpc-update</tt> command returns the error <code>"I don't think you're connected to the internet."</code>, you may need to open TCP port 873 (rsync) on your firewall for the outbound connection.


=== Offline upgrade ===
== Step 4: Update activities ==
[[Image:YamaDone.JPG|thumb|''for new users'' [[USB_upgrade|<br>'''illustrated guide to upgrading using a USB stick<br>''']]]]
You can use another computer that is connected to the internet (a desktop at home, a computer lab, etc.) plus a USB storage device (such as a compatible [[USB_drive#USB_drives_and_firmware|USB flash drive]]) to upgrade your XO.
The way it works is on your non-XO computer you download two files containing the upgrade data, saving them to the USB flash drive; then you insert the USB flash drive into your XO and trigger its upgrade process.
'''Note that this process will COMPLETELY erase ALL files on your XO! Make sure you have backed up any files you want to save!'''


Plug an empty formatted USB flash drive into the computer that is connected to the internet.
After you reboot the first time, sugar should notify you that your activities should be updated. Your activity update process will differ depending on whether or not you have network access.
Then, right-click (Ctrl-click for Mac) on each of the two URLs below and choose "Save Target As" ("Save Link As" for Firefox). Save both files to the USB flash drive. Do not open the files.


* http://download.laptop.org/xo-1/custom/g1g1/gg-767-4/fs.zip (This file contains only instructions for the firmware to update with the following file.)
[[Image:820_firstactivityinstall.png|thumb|G1G1 Activity install]]
* http://download.laptop.org/xo-1/custom/g1g1/gg-767-4/gg-767-4.img (This file contains the Sugar platform with the G1G1 2008 set of Activities.)
[[Image:820 updateproposal.png|thumb|Activities update proposal]]


The first file is about 297 KB, and the second file is quite large (about 450 MB), so they might take a while [15 - 20 min.] to download. When the download is complete, Eject/Remove the USB flash drive, and unplug it. After you have finished this step, there should be two files on the USB flash drive, the <tt>fs.zip file</tt>, and the <tt>.img</tt> file. The MD5 checksum for fs.zip is 1bb452e77b7390e00bdd7fdcc7cbc793 The MD5 checksum for gg-767-4.img is 3f281dda352d32320879728377b32476
=== With the XO connected to the internet ===


Now, follow the steps below to complete your installation:
First, '''connect to the internet''', and then either click the "Check now" icon in the update notification dialog, or, if you've dismissed the dialog, open the sugar control panel and click the "Software update" module.


# Turn off your XO and connect your USB flash drive to it.
You should see a progress bar as your XO looks for the appropriate updated versions of the activities you have installed. When it is done, click "Install selected" to update your activities. You'll see another progress bar, as the activities are updated.
# Make sure your XO is plugged in.
# Hold down all four gamepad keys (on the right side of the screen, above the power button). While still holding the four gamepad keys, push the power button to turn the XO on. Keep holding down the four gamepad keys until the message "Release the game key to continue" appears on the screen.
# Release the gamepad keys. If you see a grid of colored boxes on your screen, congratulations! Your XO is reflashing. It will take about 10 minutes and your XO will automatically reboot when it is done. Your XO may reboot twice, playing the little XO tune.
# After your XO reboots, the last step is to update to the newest versions of Activities. When the XO boots you will see a bar toward the top of the screen that says "Software Update" and the options being "Cancel", "Later" and "Check now". Before you choose "Check now" to update the activities, you must reconnect your XO to the internet. You may see the sign-in box appear in home view. If it does, and it lists your router, you can do it from there. If it doesn't appear or offers the wrong connection, go to the Neighborhood view and connect from there. Then go back to Home view and then click "Check now" (it's ok to leave the home view because when you go back the options should still be there). First the XO will check for any updates and then it asks if you'd like to install them. Click "Install selected" to install the newest versions of your activities. <br>
Congratulations, you've upgraded!
Now, you should be ready to go. Have fun!


(If you chose "Later" on the software update, go to the Sugar Control Panel and select the "Software update" when you are ready to install the updates)
Some activities may not successfully update, either because the new version of the activity is improperly packaged or due to transient network errors. If this is the case, some activities will remain in the "available updates" list after the installation process has completed. If a network error was the cause, you may wish to immediately retry the installation; otherwise, you probably need to wait until the activity author uploads a corrected version of their bundle.

=== Without the XO connected to the internet ===
If you do not have a connection to the internet:

:1. Download the [[G1G1 Activity Pack]] (from [http://wiki.laptop.org/images/6/62/G1G1_Activity_Pack_1.zip here]) and unzip it in the base (root) directory of a BLANK USB flash drive. You should see two directories (boot and bundles), and a file called customization-2 in the base directory. <br>
/boot
/bundles
customization-2
:2. Insert the USB flash drive and [[reboot]] the XO. It will display text on a black screen as the activities are installed, after which it will power off.<br>
:3. Remove the USB flash drive.

'''Notes'''
* The USB flash drive should be formatted with a VFAT file system (FAT16 with long filename support); this is the common format for most USB sticks with capacity up to 2 GB.
** It is important that the USB flash drive have a partition table, and that the VFAT file system be in the first partition. Linux allows you to put a file system directly on the drive itself without a partition table (i.e. "mkfs.vfat /dev/sdi", rather than fdisk and "mkfs.vfat /dev/sdi1"), but then on boot, the XO will panic with an error from mount ("non-zero status code 255").
* You can perform steps 1 and 2 on another computer, or if you are familiar with the Linux command line, on the XO in a [[Terminal Activity|terminal]] using <tt>wget</tt> and <tt>unzip</tt>.
* Commands such as "extract here" in ubuntu / windows will sometimes create a directory with the same name as the zip file, placing the unzipped files within it. If this happens, you will have to move the files to the base directory in order for your XO to see them on boot.
* The "boot" directory will contain two zip files, actos.zip and runos.zip. This is normal; these files SHOULD NOT be unzipped.
* Warning: the USB flash drive should be empty before this operation to contain ONLY the G1G1 Activity Pack files at end.
* If your machine is not a secure XO (its firmware is unlocked), you must boot in secure mode. If you have a developer key on a removable media like an SD card or a USB key, remove the media. If the developer key is on the NAND FLASH or the machine is permanently unlocked, hold the X game key while booting.

In addition to the [[G1G1 activity pack]], some commonly installed alternative activity packs include the:
* [[Peru activity pack]]
* [[Nepal:_Testing%2C_QA%2C_and_Configuration#Nepal_Activity_Pack|Nepal activity pack]]
* [[:Category:Activity Pack|...more activity packs]]

(The Nepal activity pack contains some [[Nepal_Customization_702|additional customizations]] made by [[OLE Nepal]] for their pilot).

To install these packs, use the same process that you just used to install the [[G1G1 activity pack]].

<trac>8554</trac> Two parenthesis images now appear around an Access Point (AP) icon in the Neighborhood View to indicate which AP the XO is currently using.

= Notable Open Bugs In This Release =

For the best experience and maximum scalability with the XO we recommend the following best practices:


'''For all XOs'''
'''For all XOs'''
* If you open too many activities (generally more than 3) at once you may experience slow response. To close activities, use the frame button (upper right), hover over the open activities, and click on close.
* Restart your XO every 24 hours or less.
* In general, you do not need to double click on anything in the XO interface. It is designed for a single click. For example, double clicking to launch an activity will cause the XO to launch two instances of the activity which may cause one to fail.
* Do not open too many activities (generally not more than 3) at once.
* Drag and drop has limited support in this release. It may work in some cases but it does not work consistently everywhere.
* There are a few cases where a USB stick should not be removed even though it is not shown in the Frame. To prevent data loss, its safest to shut down your XO before removing a USB stick.
* Power save mode is still in development. In this release it is turned off by default in the control panel. If you use it and experience problems, please turn it off.
* In general, you do not need to double click on anything in the XO interface. Its designed for a single click. For example, double clicking to launch an activity will cause the XO to launch two instances of the activity.
* If the XO stops collaborating or stops responding, you can reboot it from the home screen (hover over the XO in the center) or hold down the power button for more than 6 seconds.
* Drag and drop is not supported in this release. It may in work in some case but it does not consistently everywhere.
* Ensure that you have unmounted a USB stick before removing it. Go to the Journal, hover over the USB stick icon and click on 'unmount'. Another method to remove a USB stick and avoid corruption is to power down the laptop before removing the USB stick..
* Do not turn on power save mode when the XO is connected to an ethernet cable via a USB - Ethernet adapter. You will lose Ethernet connectivity and need to reboot to get it back if the the XO sleeps when connected to a wired ethernet connection.


'''For XOs used in school with many XOs present
'''For XOs used in school with many XOs present
* For users in a school, the collaboration may become unstable after more than two hours of continuous usage. If there are a lot of XOs collaborating you may not see all the other XOs in the Mesh view. Restarting the XOs and the collaboration may help.
* Reliable collaboration using the Write activity over mesh or access point networks may not exceed two hours. If there are a lot of XOs or a lot of wireless traffic (e.g. many XOs or many access points) then Write may shut down during collaboration. In this case you may be able to reconnect Write to the collaboration in the Neighborhood view.
* When collaborating over a Mesh (i.e. XO to XO collaboration with no access point or school server) you should limit the number of XOs on any channel to 10. There are three Mesh channels available (1,6 and 11) and each should have a maximum of 10 XOs. More XOs in a channel may cause instability in the collaboration.
* Many XOs (more than 20) on the network at the same time can cause collaboration and wireless networking to fail. For best results have users who are not collaborating turn off their radios via the Network panel in the main Control Panel.

== General Issues ==
All known open bugs (defects) in this release are [http://dev.laptop.org/query?status=assigned&status=new&status=reopened&order=priority&col=id&col=summary&col=status&col=type&col=priority&col=milestone&col=component&type=defect here]

This is an open bug tracking system so anyone can enter bugs. Therefore, please use caution when interpreting the content of these bug reports. If you have a question about the validity or status of any known bug you e-mail the owner by leaving a comment in Trac (click on the bug ID to bring it up on Trac). You can also send an e-mail to devel@lists.laptop.org.

* <trac>6253</trac> You must close the original activity before opening a file created by it in another activity, when using the Journal. For example, if you take a picture in Record, then go to the Journal and choose open in Paint from the drop down menu, it will open again in Record. The workaround is to close the original activity (e.g. Record in this example) before opening it in a different activity.
* <trac>6388</trac> You cannot use a USB and SD card at the same time. It must be one or the other.
* <trac>7426</trac> Journal disappears after downgrade from 8.2 to 70x.
* <trac>7509</trac> After installing XO software from a USB stick a corrupted file (.olpc.store) sometimes gets left behind. If this happens you will not be able to see the USB stick on the XO until you remove that file.
* <trac>7531</trac> and <trac>7812</trac> If the XO fails to shutdown from the XO menu, you may need to shut it down by pressing the power button.
* <trac>7642</trac> and <trac>7990</trac> and <trac>8577</trac> When the Control Panel is open, changing the Home view style or open the Frame may not work as expected.
* <trac>7713</trac> You cannot re-install an activity of the same version with the Software Updater. You must remove it first and then re-install it via Browse or Activity packs. The Software Updater will only install newer versions of existing activities.
* <trac>7742</trac> and <trac>7876</trac> Double clicking to launch activities will cause two instance to launch.
* <trac>7785</trac> There are some reported problems with connecting to a network via USB to Ethernet adapter. This bug tracks one and see the power section below for another.
* <trac>7895</trac> and <trac>7993</trac> and <trac>8099</trac> Some USB sticks will not show up as mounted in the Journal. Its safest to shutdown your XO before removing a USB stick, even if it does not appear in the Journal or Frame.
* <trac>7922</trac> Do not turn on power save mode when the XO is connected to an ethernet cable via a USB - Ethernet adapter or your XO may stop working when it suspends.
* <trac>8011</trac> If you remove an activity, you must restart the XO before trying to re-install it via the Software Updater.
* <trac>8088</trac> Some Kingston usb keys aren't mounted and can't be used to distribute activation leases.
* <trac>8423</trac> Moving a lot of icons in Freeform of the Home view can cause extra memory to be used. This may cause your XO to become unstable. The workaround is to reboot your XO after moving the icons.
* <trac>8452</trac> If both the Screen rotation button and the Frame key are pressed multiple times the XO may become unstable.

* <trac>8533</trac> Extra entries in journal after upgrading from 656
* <trac>8613</trac> When using the olpc-update command you may get messages on the screen. These can be ignored if the update succeeds.
* <trac>8606</trac> Drag and drop to and from clipboard is not consistent. Using control-c top copy to clipboard and control-v to paste from it are more reliable.

== Open Power Issues ==
* <trac>6201</trac> eToys can stop working if it is playing a sound when the XO suspends. See more details on when the XO suspends [[Release_Notes/8.2.0#Longer_battery_life|here]].
* <trac>6467</trac> When an XO wakes up it may take some time before all available XOs and activities are shown in the Neighborhood.
* <trac>8443</trac> After the XO wakes up from closing the lid, the battery charged level may take some time to update. The correct battery usage level should appear after the XO discharges an additional 1% of battery power.
* <trac>8490</trac> Sometimes the screen will flash when coming out of sleep (screen black). This may indicate an unstable condition and may require a reboot.
* <trac>8592</trac> When waking from sleep, the XO will try to connect to a Mesh (e.g. another XO). If that fails it will next try to connect to the wireless AP used. You must until it fails or succeeds in connecting to the AP before manually choosing an AP from The Neighborhood view. If you maually connect before its done, you may get two network icons (a false one showing a Mesh connection and a real one showing the wireless AP connection).
* <trac>8632</trac> Sometimes when the battery completely runs out of power, the XO will not recharge. The workaround is to remove the battery then plug the XO then replace the battery.

== Open Network and Collaboration Issues ==
Explain scale and how to turn off the radio. <br>

* <trac>5501</trac> it takes some time for the link-local presence information to stabilize.
* <trac>6448</trac> must use mesh or AP but not both.
* <trac>6944</trac> If you click on a second AP while waiting for the first AP to connect the UI may confuse which is connected.
* <trac>7511</trac> Transferring video files between laptops saturates bandwidth and kills running session
* <trac>7513</trac> Sharing is limited in time. Cannot share overnight
* <trac>7764</trac> connect to a schoolserver using the 'Register' option in the xo-palette on the home-view. open a terminal activity and use the command line interface of the control panel to reset the registration 'sugar-control-panel -c registration'. After restarting sugar try to connect to the school server again.
* <trac>7825</trac> Some WPA access points may not work. We have identified that the XO is incompatible with certain access points running WPA encryption. The workaround is to use another encryption scheme such as WPA2 (RSN) or WEP.
* <trac>7893</trac> It takes some time for XOs to appear and disappear when changing mesh.
* <trac>8121</trac> There is a point when launching new activities fills up mem, makes system crawl to a freeze, and only solution is to power down
* <trac>8160</trac> Write activity stops sharing and hides users from neighborhood
* <trac>8168</trac> cloaked WPA network appears, then disappears after connection attempt
* <trac>8189</trac> Maximum # of XOs in a mesh is 10

The contents of this page are considered outdated and some of the information may be stale. Please use information here with caution, or update it.
  This page is monitored by the OLPC team.
  For the general public

Our apologies, but if you are using Browse in version 10.1.1 on XO-1.5 you may have been directed to this page by mistake. If so, please go to the 10.1.1 release notes. The rest of this page relates to version 8.2.0.

Before you update to this release

  • If you are in a school or other deployment, make sure you contact your technical support team before updating. Some deployments have special configurations which will need special steps taken before update. Your deployment may not yet support this release.

New features in 8.2.0

There is a new Help Activity in this release that includes a full manual on the laptop. Look for the icon of a Question Mark.

In addition to fixing bugs, we've added lots of new features to our 8.2 release, including

The new XO manual for release 8.2.0 is available here.

Upgrading from previous releases

For technical details and other upgrade options see olpc-update and Clean-install procedure. If you run into trouble, see Upgrade troubleshooting, Support FAQ and Support to email our tech support volunteers.

If your XO is connected to the internet

Note that this process may make some of your Activities and the Journal items that depend on them not work - make sure you have backed up any files you want to save!

This process can take more than 30 minutes, much longer if you have a slow internet connection.

  1. Make sure your XO is plugged in, turned on, and connected to the Internet (you should be able to load http://laptop.org in the Browse Activity). If your XO is not connected to the internet, you will not be able to use this upgrade method.
  2. Open the Terminal Activity. Activity-terminal.svg You can find it by going to the home view (press the 5th symbol from the left, top row), clicking on the little arrow at the bottom right of the screen, and then on the symbol that looks like this one.
  3. In the Terminal Activity, type su - (lowercase letter 's', lowercase letter 'u', a space, and a hyphen). Press Enter.
  4. At the "-bash-3.2#" prompt type olpc-update 767. Press Enter.
  5. You should see text that looks something like this (sometimes, in addition to the text below, you might get a message about irsync_pristine failing, and that "irsync_dirty" is being tried, this is normal):
 Downloading contents of build ''{{:Friends in testing/current image}}''
 Updating to version hash ''xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx''
 Making clean /versions/updates/xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
 Trying irsync_pristine update from rsync://updates.laptop.org/''build-{{:Friends in testing/current image}}''
 - Cleaning tree.
 - Fetching contents.
 - Performing incremental rsync. [Comment: Wait a long time! Could be over an hour depending on your internet connection speed.]
 Verifying update.
 Installing update in /versions/{pristine,run}/''xxxx''

6. At the end of the upgrade, you will either see the words "Installing update in...." or "Update Succeeded!" on the screen. If you see the words "I don't think you're connected to the internet." see the notes below.

7. Wait for the prompt "-bash-3.2#" and type reboot then press Enter to restart your XO. You will probably hear the little XO tune 2 times, then it will say erasing and a countdown will appear. Finally it will reboot again, you will hear the tune for a third time. Now you are ready to go to step 8.

8. After your XO reboots, the last step is to download the new versions of Activities. When the XO boots you will see a bar toward the top of the screen that says "Software Update" and the options being "Cancel", "Later" and "Check now". Before you choose "Check now" to update the activities, you must reconnect your XO to the internet. You may see the sign-in box appear in home view. If it does, and it lists your router, you can do it from there. If it doesn't appear or offers the wrong connection, go to the Neighborhood view and connect from there. Then go back to Home view and then click "Check now" (it's ok to leave the home view because when you go back the options should still be there). First the XO will check for any updates and then it asks if you'd like to install them. Click "Install selected" to install your newest versions of your activities.

Congratulations, you've upgraded!

Note:

  • When upgrading from build 703 or 708 you will not see the Library (links to science, books, etc links on the left side) in the Browse home page. You can re-install the Library as follows:
    • Open the Control Panel and go into Software update.
    • After it checks for updates, go to "Modify activity groups" and click on the triangle.
    • Beside "Group URL" type: http://wiki.laptop.org/go/Activities/G1G1 and click the "Add" button.
    • Click "Refresh" and allow the XO to upload the new updates.
    • Click on Install selected. Once it completes, reboot.
  • If you can browse the Internet (see step 1 above) but the olpc-update command returns the error "I don't think you're connected to the internet.", you may need to open TCP port 873 (rsync) on your firewall for the outbound connection.

Offline upgrade

for new users
illustrated guide to upgrading using a USB stick

You can use another computer that is connected to the internet (a desktop at home, a computer lab, etc.) plus a USB storage device (such as a compatible USB flash drive) to upgrade your XO. The way it works is on your non-XO computer you download two files containing the upgrade data, saving them to the USB flash drive; then you insert the USB flash drive into your XO and trigger its upgrade process. Note that this process will COMPLETELY erase ALL files on your XO! Make sure you have backed up any files you want to save!

Plug an empty formatted USB flash drive into the computer that is connected to the internet. Then, right-click (Ctrl-click for Mac) on each of the two URLs below and choose "Save Target As" ("Save Link As" for Firefox). Save both files to the USB flash drive. Do not open the files.

The first file is about 297 KB, and the second file is quite large (about 450 MB), so they might take a while [15 - 20 min.] to download. When the download is complete, Eject/Remove the USB flash drive, and unplug it. After you have finished this step, there should be two files on the USB flash drive, the fs.zip file, and the .img file. The MD5 checksum for fs.zip is 1bb452e77b7390e00bdd7fdcc7cbc793 The MD5 checksum for gg-767-4.img is 3f281dda352d32320879728377b32476

Now, follow the steps below to complete your installation:

  1. Turn off your XO and connect your USB flash drive to it.
  2. Make sure your XO is plugged in.
  3. Hold down all four gamepad keys (on the right side of the screen, above the power button). While still holding the four gamepad keys, push the power button to turn the XO on. Keep holding down the four gamepad keys until the message "Release the game key to continue" appears on the screen.
  4. Release the gamepad keys. If you see a grid of colored boxes on your screen, congratulations! Your XO is reflashing. It will take about 10 minutes and your XO will automatically reboot when it is done. Your XO may reboot twice, playing the little XO tune.
  5. After your XO reboots, the last step is to update to the newest versions of Activities. When the XO boots you will see a bar toward the top of the screen that says "Software Update" and the options being "Cancel", "Later" and "Check now". Before you choose "Check now" to update the activities, you must reconnect your XO to the internet. You may see the sign-in box appear in home view. If it does, and it lists your router, you can do it from there. If it doesn't appear or offers the wrong connection, go to the Neighborhood view and connect from there. Then go back to Home view and then click "Check now" (it's ok to leave the home view because when you go back the options should still be there). First the XO will check for any updates and then it asks if you'd like to install them. Click "Install selected" to install the newest versions of your activities.

Congratulations, you've upgraded! Now, you should be ready to go. Have fun!

(If you chose "Later" on the software update, go to the Sugar Control Panel and select the "Software update" when you are ready to install the updates)

Resolved bugs in this release

Many bugs were closed in this release. A few important ones include:
<trac>5156</trac> Browse can view Google calendar.

<trac>5613</trac> The XO name can now accept any characters. This is important for languages which do not use the ASCII characters.

<trac>6014</trac> Activities try to save their data when the XO is shut down while an activity is open. This is better but not complete. Users should close their activities before shutting down the XO.

<trac>7480</trac> You can reset your network history in the Network control panel in case you need to remove old configurations. However, you will need to re-enter all AP passwords after doing this.

== Notable open bugs in this release ==<nowiki>Insert non-formatted text here</nowiki>

For the best experience and maximum reliability with the XO we recommend the following best practices:

For all XOs

  • If you open too many activities (generally more than 3) at once you may experience slow response. To close activities, use the frame button (upper right), hover over the open activities, and click on close.
  • In general, you do not need to double click on anything in the XO interface. It is designed for a single click. For example, double clicking to launch an activity will cause the XO to launch two instances of the activity which may cause one to fail.
  • Drag and drop has limited support in this release. It may work in some cases but it does not work consistently everywhere.
  • Power save mode is still in development. In this release it is turned off by default in the control panel. If you use it and experience problems, please turn it off.
  • If the XO stops collaborating or stops responding, you can reboot it from the home screen (hover over the XO in the center) or hold down the power button for more than 6 seconds.
  • Ensure that you have unmounted a USB stick before removing it. Go to the Journal, hover over the USB stick icon and click on 'unmount'. Another method to remove a USB stick and avoid corruption is to power down the laptop before removing the USB stick..

For XOs used in school with many XOs present

  • Reliable collaboration using the Write activity over mesh or access point networks may not exceed two hours. If there are a lot of XOs or a lot of wireless traffic (e.g. many XOs or many access points) then Write may shut down during collaboration. In this case you may be able to reconnect Write to the collaboration in the Neighborhood view.
  • When collaborating over a Mesh (i.e. XO to XO collaboration with no access point or school server) you should limit the number of XOs on any channel to 10. There are three Mesh channels available (1,6 and 11) and each should have a maximum of 10 XOs. More XOs in a channel may cause instability in the collaboration.


  • Please see the Deployment Support pages for information on collaboration and connectivity in schools or areas that are densely populated with XOs.
