Bug Description

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 occurs 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

Hardware: Thinkpad Edge 14
Architecture: x386

I had the same experience on similar hardware. Also adjusting brightness from keyboard is buggy. When decreasing brightness, the indicator bar reaches the bottom before the brightness is minimum. Likewise when increasing brightness, the indicator bar reaches the top before brightness is maximum. I downgraded to an earlier kernel which does not have these problems (2.6.32-23-generic-pae). Therefore this may be a regression.
