Well, I was wrong; I'm not able to reinstall the video driver yet. After I uninstalled the old driver, I tried to install the new one. It told me the new one was an x86, whereas I have the 64-bit Oneiric installed. So that file was one I had downloaded a couple of months ago and it is the wrong one. So I switched over to my Windows machine and downloaded the 64-bit driver to both my USB drive and my SD card. When I tried to mount each of those on the Ubuntu computer, I got an error saying that I needed to specify the filesystem type. I did the mount command again with the filesystem type, msdos, and it told me that I have a bad superblock on both drives. I am quite certain this is not true because the USB drive is totally new. Someone palease help me fix this drive issue, and I really think I can take it from there.
I just thought of something. Is there any way to download the driver from the NVIDIA website using the console commands? I've never done that before, and I don't know how.
Check those and see if any one could help you out...Goodluck.
The real source of most of my trouble in this was the continued failure of my USB drive and SD card. I may have to start another thread to find the problem with those if I can't find some good advice elsewhere in the forums.
