After a reboot Ubuntu 12.04 is using VESA instead of Intel Driver. I noticed it because of low resolution.

My System (hwinfo)

My Xorg.0.log

I cant find anything abnormal in the Xorg.0.log except that my system favours to load VESA instead of Intel drivers. Iam not such a geek whos able solve this by his own. Please give me a hint to get a step further.

Thank you
