  Binary package hint: xorg
  
  After upgrading from lucid the laptop screen flickers similar to a CRT
  with a low refresh rate, i.e. fast, small changes in lightness
  especially visible in gradients. The flickering occours independently
  from the chosen display resolution or brightness.
  
  Other observations:
  - when I connect an external display via VGA the flickering disappears on both displays
  - gnome-display-properties lists the native resolution twice, of which one additionally introduces a pattern of blurred vertical stripes

  Thinkpad Edge 15
