** Description changed:

  Binary package hint: xorg
  
  When plugging in an external LCD Screen (LG Flatron L1915S) into my
  Thinkpad R60 Laptop, it works only very inconsistently. What happens is
  that the screen shows for a split-second and then goes dark.
  
  This behaviour occurs sometimes when resuming from hibernation, or just
  when hotplugging the screen. I even had it when booting up with the
  screen connected. I am finding it difficult to pinpoint the exact
  conditions of the error.
  
  Further, when it does work, as soon as I plug in the external screen,
  all desktop effects are disabled, and I have to enable them again. Also,
  Desktop effects don't work when displaying on both screens.
  
  The bug report command was run at a time where the external monitor was
  working.
