** Description changed:

  Binary package hint: xserver-xorg-video-intel
  
  Sometimes after login, when I do an xrandr (workaround to bug #617421 )
  the notebook screen is black (happens only when no external monitor is
  attached). I can see the mouse pointer moving but that's it.
  
  I was about to file that for gdm package, but I am not sure what package
  is responsible for this problem.
  
  When that happens and I do (in blind attempt) start the console and
  execute xrandr (to reevaluate screens) does not help either. Switching
  CTRL+ALT+F1 and CTRL+ALT+F7 back and forth does not help either.
  
  Switching to a text login, logging in and doing "restart gdm" then
  helps.
  
  Last time it happened I did  xrandr --current >xrandr-output.txt in a
  blind attempt and then looked at it after gdm restart. I found that also
  the TV1 was again active (which is the main issue of bug #617421
  mentioned above). Probably it has to do with this. Probably TV1 was
  guessed to be the main screen but anyway LVDS1 was shown active true
  (see attachment).
