== Purpose ==

An update to software release [[Release_notes/10.1.1|10.1.1]] for [[XO-1.5]] laptops that is also available for [[XO-1]] laptops.
It is the first release to bring the Fedora 11 base operating environment, Sugar v0.84, and the Gnome desktop to XO-1 laptops.

== Installation ==

=== XO-1.5 ===

{{Software_Install|path=http://build.laptop.org/10.1.2/xo-1.5/os852|release=10.1.2|build=os852|model=XO-1.5|signed=yes}}

=== XO-1 ===

{{Software_Install|path=http://build.laptop.org/10.1.2/xo-1/os852|release=10.1.2|build=os852|model=XO-1|signed=yes}}

== Update ==

You may wish to update from a previous version of the operating system. This method preserves most user data, Sugar journal and installed Sugar activities, but does not preserve certain operating system customisations such as additional packages.

(Update is distinct from install. If you have followed the install procedures above, then you need not follow this section.)

=== Compatibility ===

A few previous versions do not support this method.
Here are the known working update combinations:
*release 8.2.1 (build os802.img and gg-802-1.img) to release 10.1.2 on XO-1,
*release 10.1.0 to release 10.1.2 on XO-1.5,
*release 10.1.1 to release 10.1.2 on XO-1.5.

We have tested online update from 8.2.1 (<trac>10278</trac>). It requires roughly 470MB of free space, 350MB of downloads, and five hours on a high latency connection.

We have tested offline update from 8.2.1. It requires roughly 470MB of free space, 914MB of downloads, and roughly 50 minutes on a laptop with no journal entries.

Following update of the operating system, [[Software update]] of activities may require as much as 220MB again depending on what is selected. For release 8.2.1 (build gg-802-1.img) to release 10.1.2 on XO-1, there is not enough free space with the default list of activities, you must delete some first, or remove the [[Olpc-update#Purging_a_previous_OS|previous operating system version]] before running [[Software update]]. See <trac>10278</trac>.

(Because of the time and download cost, it may be more appropriate to install afresh, which is roughly 700MB of downloads and no more than about twenty minutes of installation.)

=== Known Problems ===

After an operating system update there are a few known problems:
*all known wireless access points are forgotten, and you must choose an access point again,
*the Browse activity will not start, and must be updated with the [[Software update]] icon in ''My Settings'' before it will work again,
*the "Journal is full" message is likely to appear if not enough space has been made prior to update, and you may need to remove journal entries, activities, or the [[Olpc-update#Purging_a_previous_OS|previous operating system version]] to bring the system back to normal operation.

=== Preparation ===

To prepare for an operating system update:
*remove as much saved content as you no longer need,
*remove any large activities you no longer need, and;
*use [[Software update]] to ensure the Terminal activity is the latest available version.

Follow the instructions in one of the subsections below, according to which method and laptop model you are using.

=== Simple Online Update ===

*establish an internet connection from the laptop (if you plan to do online update),
*start the laptop normally,
*start the [[Terminal Activity]], and depending on the laptop model type:

==== XO-1.5 ====

sudo olpc-update 10.1.2_xo1.5-852

==== XO-1 ====

sudo olpc-update 10.1.2_xo1-852

See [[Olpc-update#Simple_online_update|Simple Online Update]] for more detail about the method.

=== Simple Offline Update ===

*download a .usb file,
**for XO-1.5 [http://build.laptop.org/10.1.2/xo-1.5/os852/os852.usb os852.usb],
**for XO-1 [http://build.laptop.org/10.1.2/xo-1/os852/os852.usb os852.usb],
*put it on a [[USB drive]],
*boot the laptop normally,
*plug the USB drive into the laptop,
*start the [[Terminal Activity]], and type:

sudo olpc-update --usb

See [[Olpc-update#Simple_offline_update|Simple Offline Update]] for more detail about the method.

== New features ==

For new features relative to 8.2.1, please see the New features sections of [[Release_notes/10.1.0|10.1.0]] and [[Release_notes/10.1.1|10.1.1]]. New features relative to 10.1.1 are:

* support for XO-1.5 HS (High School) laptop.

No other new features were added.

== Known Problems ==

=== XO-1.5 No screen rotation ===

The screen rotation key (on the bottom left of the display) does not rotate the screen image. It is safe to use, but makes no change.

Developers are working on rotation support in the graphics driver. (<trac>9350</trac>)

=== Record activity video recording may pause ===

When recording a video of a very complex natural scene, such as moving vegetation, the recording may pause. If this happens, reducing camera movement may allow the laptop to catch up. The pause is visible on playback.

On XO-1.5, switch to ''Low'' quality and try again. XO-1 only has ''Low'' quality.

On XO-1.5, the class of SD card ordered by the deployment will have some bearing on the video recording performance. Lower class cards such as Class 2 are more likely to experience pauses during recording. Higher class cards such as Class 6 are less likely to experience pauses.

In the previous release 8.2.1, the pause was spread throughout the recording, lowering the effective frame rate. In this release the frame rate is kept as fast as possible until the pause is unavoidable.

=== XO-1.5 Record activity preview black on lid close and open ===

With the Record activity on screen displaying a preview of the camera image, closing the laptop lid for long enough to cause a suspend, and then opening it, results in the preview going black.

If this happens, the preview can be restored by pressing Alt/Tab, or switching between Sugar views using the keyboard keys or the frame icons.

The black preview does not affect the taking of photographs, or recording of video. If a video recording is being made, there will be a segment of time missing in the playback.

Developers are aware of the problem. (<trac>10068</trac>)

=== Some Language Support Removed ===

Your language preference may not be available in the Sugar -> My Settings -> Language control panel icon.

Compared to the previous 8.2.1 release for XO-1, this release removes several languages that are not required by the current mass deployments of XO-1.5, in order to conserve disk space on the smallest configuration that can be ordered. The languages Italian, Greek, Thai, Japanese, German, Telugu, and Turkish were among those removed. 150Mb was conserved. This was tracked in <trac>9982</trac>.

These languages can be added back by small deployments that require them, by [[OS_Builder|regenerating the build]].

=== CUPS Documentation ===

If CUPS is to be installed, the documentation used by the web browser won't be available. To fix this, remove the _excludedocs macro from /etc/rpm/macros.imgcreate before installing CUPS. <trac>10283</trac>.

== Bugs fixed ==

Compared against 8.2.1, the bugs fixed were not thoroughly tracked, but they include many fixes by community volunteers and Sugarlabs. Some of these fixes entered community builds that were released between 8.2.1 and 10.1.2.

Compared against 10.1.1, the bugs fixed are listed below in each of the following builds.
