Running, but not hogging the cpu:

root at antares:~# ps auxwww | grep X
root      7408  1.1  3.2  34952 25024 tty8     Ss+  19:30   0:02 /usr/bin/X :0 -br -verbose -auth /var/run/gdm/auth-for-gdm-1bXWHA/database -nolisten tcp

I forgot to mention that the display doesn't come up again even if I re-set to fbdev in xorg.conf and kill this process.  I always have to reboot.  The keyboard is still active, and apparently I can also switch to a console (e.g. <ctrl><alt><f1>).  If I logged on there before launching X, I could blindly type "reboot" to reboot the box.

Apparently, the latter two lines were created when trying to launch the accelerated config (I booted first with fbdev).

Thanks,
Albrecht.
