I posted this on a different forum with no response I think this is a common problem so I will try it here.

I have a Toshiba 5105-S501 I installed slackware 10 successfully in this system. (completely rid of windows) Anyway everything works I am watching dvd's burnin cd's etc.
The only bug is when I use the NVidia drivers I get a quarter inch black strip on the right side of my screen. If I don't run the NVdia drivers OS fills the screen and everything is normal, but I loose the ability to watch dvds and everything graphically slows down. I was wondering if anybody has any ideas to try, or if somebody has ever actually figured this out yet.
