I upgraded my Ubuntu 12.04 (which was working good!) to 12.10 the last week. During the first days everything was fine... then my monitor started flickering on colors. This happend after a ruby upgrade, but i think this is not related to my problem.

I thought it was a video problem (a note: i got optimus so i use bumblebee): so i tried to update everything graphics related usinig xorg-edgers ppa but nothing changed.

I can't think where to go now. Maybe I need to downgrade?

I'm on Alienware M17xR4 with NVIDIA GTX660M and Intel Graphic chipset. xorg-edgers ppa is enable and bumblebee is too of course!

Thanks in advance
