Hi,

I am running a HP NC6220 also with the i915 driver on Ubuntu Karmic 9.10. For me there are similar problems as the ones above. After opening the lid again (or only touching the screen off sensor which happens a lot with this laptop model) the screen flickers insanely and the mouse moves around. X seems to take a high CPU load as some windows hang on redrawing.

I checked the upstream bug and saw a hint to the /proc/acpi/video/.../DOS setting (although I have no idea what it is)

When I do a "echo 6 > /proc/acpi/video/<YOUR DEVICE HERE>/DOS" the problems dissappers instantly. and I can also close and open my lid as I want.

I checked and before the lid close it was on 0.

Does anyone know if there is a trouble when leaving this on 6, or setting it on 6 after boot automatically?
