[Edit]
This bug has been around for a bit over 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 most people, it makes the desktop unusable.
Workaround: *Note: This is a workaround, not a fix. It will give you a
usable system.
[Natty]: Regression: This workaround now only provides 2d/software rendering,
and one must either:
* Choose choose the "Ubuntu Classic" session from the GDM Login screen
or
* Install the "unity-2d" package.
[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, but brings your desktop to a
workable state.
Freedesktop.org has dealt with one bug having to do with graphics corruption on
the rs690m. That bug has been fixed, but the issue of graphics corruption in
general has not been resolved. A new bug has been opened with freedesktop.org
to continue pushing through the resolution of this issue.
