How can I get my graphics card to be recognized in System Info?
I have Intel Graphics Card, which have model number GM965. It is on a Notebook, (Lenovo 3000 Y410).
My Ubuntu Installation worked good until I upgraded to 12.04. It was a fresh install. The Graphics performance is poor compared to Natty, Oneiric. In the details tab of System Settings, Graphics driver is shown as "Unknown". I have upgraded the xserver-xorg-video-intel package to version 2.19.. from 2.17. But still same.
So, My question is Is there any other method to fix the problem with graphics showing as "unknown"?
