Hi everybody. I purchased a new laptop, I have a fujitsu siemens xi3650,
equipped with an nvidia geforce 9600m gt video card. It was Winzoz Vista pre-installed, (for those who are not italian, the -zoz suffix means something of a ****-like quality).
Needless to say that I formatted the HD and installed a LTS 8.04 ubuntu OS.

I installed the restricted extras package, but I can't get my video card working.

I tried to run the System/Administration/Hardware testing Utility, which tests my sound card, detects my screen resolution but, when start testing my video card, my screen turns black, and my laptop freezes.
I can only force quitting the laptop, no other way than cutting off the power.

With my laptop I cant see any video, dvds, avi, flv files and so on, if I try, the screen goes black, and my laptop freezes.

I tried to install the nvidia proprietary drivers, but after restarting the laptop, it can't recognise the screen resolution, and set the resolution on 640x480,

Is there any saint out there who can help me?

Please..

if you need more hardware information, please ask, I try my best (as a newbie)
genni.
