Public bug reported:

Binary package hint: xserver-xorg-video-nouveau

When the system tries to start gdm, it hangs and reports that the
graphic settings could not be loaded and asks between few options (error
tracking, terminal,...). The only working option is to continue in low
graphic mode.

The xserver log shows:

(II) NOUVEAU(0): Opened GPU channel 1
(II) NOUVEAU(0): [DRI2] Setup complete
(II) NOUVEAU(0): GART: 64MiB available

Segmentation fault at address 0xc4

Caught signal 11 (Segmentation fault). Server aborting


The low graphic mode means for me a resolution of 1280*1024@60Hz without the possibility to change it. Please help to fix this bug before I get blind (my screen is a monitor and the refresh rate of 60 is too low).
