[Launchpad Bug Tracker <556782@xxxxxxxxxxxxxxxxxx>]

You have been subscribed to a public bug by Brian Visel (eode):

[Edit:]
This bug has been around for almost a year now, and has gotten rather long, so this is a brief summary.
There is a memory corruption issue that affects users of the rs690m, to varying degrees.
For many, if not most, it makes the desktop unusable.

There is a workaround:
Regression: This workaround now only provides 2d graphics [natty].
[code]
sudo su
echo options radeon modeset=0 > /etc/modprobe.d/radeon-kms.conf
exit
[/code]
Note that this doesn't totally fix the issue.
Also, on Natty, it causes the system to fall back to software rendering, thus preventing compositing.

Freedesktop.org has marked the bug as 'Fixed', although at present Launchpad doesn't reflect this, and the code still needs to be compiled by someone and tested.  A new bugreport will need to be opened on freedesktop.org if it doesn't work.
[/edit]

Binary package hint: xorg

I can't see things right now to report the bug, but I wanted to run
ubuntu-bugs xorg while there was a curruption present.  i'll fill out
this bug more completely later.
