Xorg crashed with SIGABRT in drm_intel_bufmgr_destroy()

[Pushpendra Kumar]

My graphics are not working as before in Ubuntu 12.04
My monitor is CRT and support display range: 1024*768@85
but now this time i can get only 1204*768@65 .
I tried xrandr to increase refresh rate from 65 to 85 but it says it's not available on size 1024*768.
One major proble is: Monitor -> Unkown

Status changed to 'Confirmed' because the bug affects multiple users.

Does it work if you try to boot an older kernel?
