Description Florian Ludwig 2009-04-13 11:55:19 UTC 
The screen only updates if the mouse is moved. If i keep my mouse moving or while typing everthing seems normal.

It seems to be related to DRI2/GEM as it only occours with 2.6.29.1 kernel but with an older one i tried that doesn't support GEM it worked fine.

I tried a lot of different settings with non working. With hotplug, without, different intel-driver settings, different synaptic settings - no combination worked so far.

I'll attach my latest try. (xorg.conf, Xorg.0.log)

System
 * Debian sid
 * linux 2.6.29.1
 * xorg/mesa 7.4
 * libdrm2 2.4.5
 * hal 0.5.12~git20090406.46dc48


Not sure its related but stuff i also encounter, maby helpful:
 * without a xorg.conf x doesnt start at all with only some stuff about framebuffer driver written to the log
 * sometimes the screensize is reported wrong (maximizing windows put them patrly out of the visible area, xrandr says something about ~1380x780 desktop size, got 1280x800)
 * setting "AccelMethod" to "EXA" leads to: http://static.ludwigf.org/stuff/exa.png

Found a workaround: suspending.

After suspending my laptop to ram and resuming, the freezing doesn't happening anymore. After a cold boot it comes back.

This is a weird one, but I think it's a dup of 20896.
