Bug Description
Binary package hint: xserver-
I just installed Maverick on a partition yesterday. Sometimes (i.e. 2 out of 5 or 6 times so far) when booting I get a "no screens" error in the log and get xorg in low-graphics mode. I booted with kernel option drm.debug=0x04 so there should be verbose mode setting information in the dmesg output.
When the problem occurs, dmesg says:

dmesg with drm.debug=0x04
I added drm.debug=0x04, since Xorg.X.log complained about
(EE) intel(0): Kernel modesetting setup failed,
but I realize it may actually just add noise in this case.
