Upgrade

You may wish to upgrade from a previous version of the XO-1.5 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.

Since activities are not updated, several known problems will remain. Most but not all of these can be fixed using Software update.

To use this method, establish an internet connection, and launch the Terminal Activity.

For XO-1, then type:

  olpc-update 10.1.2_xo1-302

For XO-1.5, then type:

  olpc-update 10.1.2_xo1.5-302

A few previous versions do not support this method.

New features

to be completed

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.

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>)
