Known Problems
Welcome Activity
The new version of Sugar does not support the Welcome activity.
Since 13.2.2. See <trac>12869</trac>.
Restricted Software
Restricted software, such as browser plugins, codecs, and so forth, are not included in the public release. Deployments who need this software should contact OLPC or make their own builds, see OS_Builder/Add_Restricted.
Also, using olpc-update on a restricted software build will remove restricted software.
Video Playback
The XO-1 cannot play some videos in the Browse or Epiphany web browsers, because the Adobe Flash plugin is no longer available for the Geode processor.
On some models, particularly XO-1 and XO-1.5, although MP4 playback support may be present with restricted software builds, the video to be played may require more processor and graphics bandwidth than the hardware can provide;
- especially with advertising or related videos elements on youtube.com,
- also inside a web browser for Khan Academy, but;
- not so much when playing the same video in Movie Player or Jukebox,
Workaround is to transcode videos to a lower bandwidth, or to pause playback and wait for advertising to finish loading.
Since 13.2.0.
Frozen Repositories
The frozen repositories have not been updated; the release was made from all Fedora 18 updates.
Since 13.2.5.
XO-4 Headphone Detection
XO-4 speakers may remain silent if headphones are removed during automatic power management suspend, or headphones may not work if they are inserted during suspend.
Since 13.2.0. <trac>12724</trac>.
Sugar Memory Leak
A memory leak is where a program allocates memory but forgets to release it.
Sugar has had a memory leak for several versions, in proportion to the number and size of icons displayed, see #4889. The cause is in Fedora 18.
The leak has negligible impact on XO-4, XO-1.75 and XO-1.5. On these laptops we recommend that you restart Sugar at least weekly.
The leak has a severe impact on XO-1. On the XO-1 we recommend that you restart Sugar every few hours, and especially after visiting the Background screen in My Settings. The leak is even more severe if the network view shows many icons.
In 13.2.7 the number of animation cycles was reduced for switching between desktop views and exposing the frame, in order to reduce the impact further.
Since 13.2.0.
