Public bug reported:
Binary package hint: xserver-xorg-video-intel
With the alpha 3 version of the Lucid Lynx live CD I get a GPU hung
shortly after the splash screen of the the desktop (KDE) is shown.
the following messages are from dmesg:
[drm:i915_hangcheck_elapsed] * ERROR * Hangcheck timer elapsed... GPU hung
render error detected , EIR: 0x00000000
i915: waking up sleeping processes
reboot required
The loginmanager then tries to respawn the xserver several times until
there is a non blinking cursor shown at the botton of the screen.
On some other boot tries with the live cd the xserver freezes completely
and it is not possible to switch to another console.
