Screen flickers, probably driver issue

[dtoffe]

Hi,
I had Debian Stable installed and the screen looked fine, after installing Mint with either Cinnamon, Mate or Gnome, the screen flickers every few seconds. My graphics card is an NVidia GeForce 9500 GT, but don't know what drivers I have installed or where to look for it. Besides, In the System - Preferences - Monitors settings, the monitor is unknow and Detect Monitors doesn't seem to find anything.
How do I know what graphic drivers I have installed ?
Cheers,
Daniel

It seems Ubuntu detects nvidia hardware and install the proper drivers, but Mint doesn't and you must install them. Tomorrow I'll try the procedure described here and mark this thread as solved if it works.

After a clean Mint install I've installed nvidia-current, ran "sudo nvidia-xconfig" and rebooted. Now the screen doesn't flicker anymore, but I'm stuck with 640x480 mode.
It would be nice if the Mint installer could detect the hardware and install the proper drivers, I'll file a bug report with this issue.
I'm posting this procedure in case it's useful to someone else.
