** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
  I just installed Maverick on a partition yesterday. Sometimes (i.e. 2
  out of 5 or 6 times so far) when booting with an external monitor
  attached I get a "no screens" error in the log and get xorg in low-
  graphics mode. I haven't seen this so far when booting without an
  external monitor, but I haven't tried many times yet. 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:
