So raely it will just freeze or when watching a vid. the screen will go black (like powersaving, but a button press will not bring it back). Will a new kernel cure this, I have 2.6.38 (I think) now? No compiling I want is through the package tool.
Hmm, can't say i've heard of this before. Is it a whole system crash or just X? Can you press ctrl+alt+f1 to take you to a terminal?
sounds like graphic driver problems, is it a desktop or laptop? Any other cards to try?
sudo apt-get install nvidia-current
X crashing with the generic driver is odd, but if the company driver will fix it ok.
