I finally got fed up with the compatibility issues between the my Riva TNT video card and Ubuntu Linux. First the kernal gets updated and the video quits working. Then after a full day of trying this and that I managed to get version 13 of the driver installed accidentally. It worked great for 2 months, I had full resolution and the computer would boot normally. Then the kernal gets updated again. Now The video is not working again and I can't get version 14 of the driver installed. Every time I try I get some kind of error. So I removed the TNT video card and put a Radeon card in. Now there are more problems stemming from the partial failed installs of the nVidia driver.
How do I remove all traces of that old nVidia driver? Thank you in advance.
