MSI GeForce 5600FX was not supported by Knoppix. I tried to type default xdrvr=vesa or xdrvr=fbdev repeat and they were not working on the PC. I had an idea to try to type linux xdrvr=vesa or xdrvr=fbdev and then they shut out my pc. The screen was blackout.

Other Linux operating systems were not supporting my new MSI Geforce 5600FX VDTR 128 MB video card.

I am waiting for a new version of knoppix supporting any new video cards.
