Purpose

Installation

XO-1.5

Installation progress will be displayed. Green colour will fill grey blocks. It will take about ten minutes. Once finished, the Ok prompt will return. Remove the USB drive. The laptop must be rebooted using bye or the power button, not with the boot command. The USB drive can be used on other laptops.

XO-1

How to install unsigned build os360 of release 10.1.3 on XO-1.

Update

You may wish to update from a previous version of the operating system. This method preserves most user data, the Sugar Journal and installed Sugar Activities, but does not preserve certain operating system customizations 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 10.1.3 on XO-1,
• release 10.1.0 to release 10.1.3 on XO-1.5,
• release 10.1.1 to release 10.1.3 on XO-1.5,
• release 10.1.2 to release 10.1.3 on XO-1.5.

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 "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 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 10.1.3_xo1.5-360

XO-1

sudo olpc-update 10.1.3_xo1-360

See Simple Online Update for more detail about the method.

Simple Offline Update

• download a .usb and .toc file,
  • for XO-1.5
    • os360.usb,
    • os360.toc,
  • for XO-1
    • os360.usb,
    • os360.toc,
• put them 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 Simple Offline Update for more detail about the method.

New features

Collaborate without infrastructure on the XO-1.5

To mimic the mesh behavior on devices where mesh hardware is not available and make the "under a tree"-scenario possible the Sugar Ad-hoc networks have been added. The feature adds three default Ad-hoc networks, for channel 1, 6, and 11. They are represented with designated icons in the Neighborhood view.

Sharing/Backup Journal entries using a mass storage device

You may now share share Journal entries with another learner using a USB drive or SD card. The user experience is: Martin wants to give a picture he has been drawing to Simon. He plugs in his USB drive and copies the Journal entry on the drive. The entry will be shown with Martin's XO color on the drive. Simon inserts the drive and copies Martin's entry into his Journal.

You can use this feature to backup Journal entries to a USB drive or SD card.

Project Sugar from your XO onto a wall

We have added support for USB2VGA adapters. You can an XO to a projector over a USB2VGA adapter and project what is on your XO screen onto a wall for many people to see.

• 

Rotate the screen

On the XO-1.5 it is now possible to rotate the screen using the designated button or the keyboard shortcut Alt-Shift-r. This allows the learners to use the XO in ebook mode.

Polishing the interaction between GNOME and Sugar

Switching between Sugar and GNOME user interfaces is smoother. Settings a user does under GNOME have no side effect on Sugar and the other way around.

The ~/Activities directory is now hidden from the user in GNOME, to prevent Sugar from becoming unusable when the directory has been erased (<trac>10531</trac>). The networking state is synchronized, changing networking in the Sugar Control Panel or the nm-applet in GNOME does not affect in the other user interface anymore (<trac>10532</trac>). The GNOME panels (<trac>10539</trac>) and the GNOME fonts (<trac>10545</trac>) are reset on next login to undo any changes.

The dialog to set a GNOME keyring password when connecting to a secure wireless network has been disabled.

Browse

Based on requests from the field we were able to improve the Browse activity in the following ways: A Home button has been added into the Browser toolbar. The button gives you the possibility to always go back to the starting page.

In the 8.2.x builds the cursor in the Browser did change while a page was loading. This important indicator has been missing in the 10.1.x builds and has now been restored.

Another important change is that images that are downloaded with Browse create a preview in the Journal.

Paint

The cursors have been cleaned up, the text tool has been improved, new effects have been added (invert colors, mirror), we show the pencil/brush size and shape, copy and paste is now working and many smaller UI fixes have been going into this release.

Read

In the new Read version scrolling in PDFs has been improved. The dpad up/down keys and the arrow up down keys will allow you to scroll. Using fn+arrow keys (Page up/Page down) will move forward/backward by bigger chunks.

Write

The copy and paste functionality for images from Browse and Paint into Write has been improved. Furthermore, images can be placed in tables now, and an option has been added to export your writing to a PDF.

Wikipedia

The page loading has been speed up and several smaller fixes have been going in the English and Spanish version of this offline Wikipedia activity.

Scratch

The new camera plugin 0.8 makes the importing from the camera on an XO-1 possible.

Activity Updates

We include the last versions of Physics, TurtleArt, Calculate, Pippy, Help and Etoys.
