** Description changed:
Running glxgears spreads the moving gears over the whole screen
past the border of the box. The same happens with screensavers
with motion. Running those screensavers can also freeze the
system. Screenshot of glxgears is attaches.
[Workaround]
For the benefit of others who find their way here via Google, here's the
smallest workaround I've found so far:
* Use dexconf to generate a minimal xorg.conf
* Edit xorg.conf and make the following changes:
- Change Driver "vesa" to Driver "intel" in Section "Device"
- - Add the following lines between Device "Configured Video Device" and
EndSection, in Section "Screen":
+ - Add the following lines between Device "Configured Video Device" and
EndSection, in Section "Screen" (note that "Depth 16" is needed only on older
intel driver (i.e. that shipped with Ubuntu 8.04 and before). Since 8.10 it's
not needed):
Subsection "Display"
Depth 16
Modes "1152x864"
EndSubSection
Use whatever you want your maximum screen resolution to be instead of
1152x864.
