** Description changed:

  Binary package hint: xorg
  
  When I leave the laptop and turn back when screen got black (blanked by
  laptop bios and not by screensaver) moving the mouse or pressing a key
  to wake it up, I can see graphics is very slow (switching between
  windows, changing desktop etc).
  
  Steps to reproduce:
  1. Disable screensaver
  2. Wait until screen becomes dark
  3. Move the mouse or press a key
  
  Graphic performance is slow and Xorg consumes a notable amount of
  processor time.
