Release notes/10.1.1
DRAFT DRAFT DRAFT
Purpose
This release has been developed as an update to 10.1.0.
Installation
Make sure your firmware is up to date. These instructions were tested with OLPC Firmware Q3A39.
The build is installed to the internal microSD device and no external device needs to be attached afterward to boot it.
ALL USER DATA WILL BE ERASED FROM THE LAPTOP!
- Prepare the USB memory stick:
- Download os203.zd (705Mb),
- Save the file to the top directory of a USB memory stick, with the name unchanged,
- Download os203.zsp.fs.zip (2.5Mb),
- Save the file to the top directory of a USB memory stick, with the name fs.zip,
- Check the USB memory stick contains at least the two files fs.zip and os203.zd.
- Prepare the XO-1.5 laptop:
- Make a copy of any data you wish to keep,
- Turn off the XO-1.5, unless it is already off.
- Insert the USB memory stick into any USB port on the XO-1.5,
- Start installing:
- Hold down all four game keys,
- Turn on the XO-1.5,
- Wait for the message Release the game keys to continue,
- Release the game keys.
Installation progress will be displayed. Once finished, the laptop will reboot. Remove the USB memory stick during or after the reboot. The USB memory stick can be used on other laptops.
If you see a message Boot failed then the USB memory stick has not been properly prepared.
Upgrade
As an alternative to installation, 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.
To use this method, establish an internet connection, then type on the Terminal:
sudo olpc-update 10.2_xo1.5-203 # updating to build 203 of 10.2
A few previous versions do not support this method.
New features
3G and GSM Support
When a USB wireless modem is attached, it can be configured and used for internet access.
- a new Modem Configuration icon is in My Settings,
- when a USB wireless modem is inserted, an icon appears in the Frame.
Acceleration of movies/video
Movies and video are now played smoothly with new Xv support in the graphics driver.
Battery monitor in GNOME desktop
A battery icon appears to the left of the date on the top right of the GNOME desktop. Notifications regarding change to battery and AC adapter state appear on the bottom right.
Method for disabling wireless
The Network icon in My Settings has a Radio checkbox that when turned off prevents the wireless from operating.
It is easy to forget that it is been turned off.
Updated Help Activity
The Help activity has been updated to include XO-1.5 features.
Notable current bugs
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 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>)
Low sound quality in Scratch activity
Sound output from the Scratch activity is, well, scratchy. Developers are aware of the problem and a fix is planned. (<trac>9375</trac>)
No NANDblaster
NANDblaster, a technology used to install OLPC OS releases on large numbers of laptops simultaneously, did not make it into this release. A development version is working. This feature is a high priority and we expect to finish it soon. (<trac>9484</trac>)
