Xorg (i810) crashes on startup after upgrade to Gutsy

[Petri Pennanen]

Binary package hint: xserver-xorg-video-i810

After upgrading from Feisty to Gutsy on a laptop with an Intel 810 grapics card, the computer freezes on startup when loading X (before GDM comes up).

A workaround is to boot into recovery mode and edit /etc/X11/xorg.conf. Replace the device driver "i810" with "intel".

On Feisty the "i810"-driver worked fine.

This a working version of xorg.conf. Only the device driver is changed from the crashing version.

I have a similar problem with a Compaq C550. The laptop hardlocks at a somewhat random time after arriving at the gdm login screen (usually once logged in). This is rather inconclusive, but the problem also seems to be accelerated by keyboard or touchpad input. Interestingly, if the laptop is booted in single-user mode (=recovery mode at grub boot screen) and the X server started by hand ("startx" as root), it never locks up.

This only occurs using the current 2.6.22-14 kernel. When booting Gutsy with the Feisty 2.6.20-15 kernel, the problem does not appear (drm module <-> X server?)
Contrary to Petri's fortune, specifying either the "i810" or "intel" server in xorg.conf does not seem to make a difference.
