Installation

XO-1.5

How to install unsigned build os302 of release 10.1.2 on XO-1.5.

The build is installed to the internal microSD device. You will need a USB drive of at least 1 GB capacity, but only for the duration of the installation.

ALL USER DATA WILL BE ERASED FROM THE LAPTOP!

  • Prepare the USB drive:
    • Download os302.zd,
    • Save the file to the top directory of the USB drive,
  • Prepare the laptop:
    • Make a copy of any data you wish to keep,

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>)

XO-1.5 Record activity video recording may pause

When recording a video of a very complex natural scene, such as moving vegetation, in High quality, the recording may pause. If this happens, reducing camera movement may allow the laptop to catch up. Alternatively, switch to Low quality and try again.

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>)
