Knoppix and Geforce 7800 GT

[ECUHITMAN]

I have a working copy of Knoppix 5.0.1 (on CD) but when I boot from it I get to the "splash" screen (the screen that shows Knoppix 5.0 with pistons in the background) but I don't see the pistons or anything the screen is, for lack of a better term, scrambled. I left it alone thinking it 'might' fix itself but doesn't. I am fairly proficient with computers and I have some minimal experience with Linux, I have tried some of the boot options I have read about online:

Knoppix noagp
Does nothing to help. The screen is still scrambled.

failsafe
Works. I can get into knoppix without any problems using the failsafe boot option, but when I do that I no longer have any internet or other "advanced" modules loaded. But still, it works.

Anyone have any other ideas that are maybe a little less restricting than failsafe? Oh by the way, my hardware works normally without any problems when in windows. So it is not a hardware problem (other than maybe a driver problem).

Here is my full system specs:

AMD 3800 X2
BFG Geforce 7800 GT
ABIT AN8
2 GB of DDR 400 Ram

Ideas?
Thanks!

Try cheatcode xvrefresh=60

It is a driver problem. Xorg will autodetect your nvidia card and assign it the nv driver. This doesn't support the newer nvidia cards well at all. You need to use some generic video card driver that can properly display the screen like fbdev or vesa. From a quick google search it looks like you can change the xorg driver at startup with what knoppix calls a "cheatcode":

knoppix xmodule=vesa

or

knoppix xmodule=fbdev

They should both work. Make sure to type in the knoppix part too though.
