Public bug reported:

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

Hardware:
Thinkpad Edge 15
