cool, i think im gonna try that tonight. i just converted my rig over to ubuntu because i took a power hit a couple weeks ago and after 20 minutes of gaming the computer locks up. so no more games for me until i buy a new card. ive been very happy with ubuntu so far. great support and ive got a billion programs running on it with no lag. i cant wait to get beryl running.

Install Nvidia GPU Drivers
Installing Nvidia’s closed-source 3D-accelerated drivers is easy with Feisty. Go to System > Administration > Synaptic Package Manager and search for the nvidia-glx package.
