  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:
