I got it working finally. But before I had to
- Remove all Linux-restricted-modules packages
- Add option "NVAGP" "1" to xorg.conf
But now I am facing a new problem here. The screen is a bit sluggish and get corrupted as soon as some animation appears. Also when I scroll, all the pixels get overlapping everything becomes messy.
I have attached nvidia-bug-report for your reference. Also attached are two screenshots which would give you the idea of screen corruption.
I noticed an error message in "dmesg", it says, NVAGP not loading since AGPGART is already loaded in the backend.
I tried with agpgart=no in grub when booting, but didnt work.
glxgears works fine without any quirks, and gives me a constant 405 FPS
What could be the reason of corruption? Is it only because of AGPGART loading in the backend? or is there any issue with my configuration?
