I have an ASUS desktop PC which is giving me an annoying video glitch

If I check card model with lspci I get:

VGA compatible controller: NVIDIA Corporation Device 0de5 (rev a1)

Apparently my Ubuntu doesn't know exactly me NVIDIA graphics card model, could that be my problem? I currently have a nvidia GeForce GT 530 on my PC.

The driver I'm using is the "post-release updates". I've also tried the recommended ones, and while the issue didn't go away, the pc seemed a bit slower.

Any advice?

i would say update to 310 drivers for nvidia.

sudo add-apt-repository ppa:ubuntu-x-swat/x-updates

sudo apt-get update

sudo apt-get install nvidia-310

Also if you're using unity, after a reboot it may be necessary to run these commands to make unity visible again dconf reset -f /org/compiz/ then setsid unity – Lemagex May 15 '13 at 9:40
I actually ended up erasing and reinstalling, because after installing a driver following some obscure tutorial, my pc was not booting up no more... thanks anyway! Not everything is allright! – alemur May 15 '13 at 23:16
