Recently my Laptop screen started to flicker.

• You can view the phenomena here: YouTube
• Sometimes the screen is totally scrambled, but most of the time it starts with the Title bar only.
• It happens inconsistently.

My Laptop is Asus UL30A and I'm using Ubuntu 11.10.

Output from command:

sudo lshw -C display; lsb_release -a; uname -a; xrandr

I already rolled back the kernel to 3.0.0-14 instead of 3.0.0-17 as mentioned in this post, but without result.

I guess the problem is related to the driver, because I don't see similar behaviour in the BIOS Setup.

Any tips or help is welcome.
