I am new to Linux, but I could not find the answer to my question in the other threads. I have a Ti 4200 X4 and when I install the tar files (4191) like the pfd file from nvidia says too...I get (after make install)*** Failed rmmod sanity check. Bailing out! *** It also says something about having to remove existing kernel and exiting X.One more side note on install of Mandrake, Geforce drivers are installed. If I change it to Geforce 4. I can't get back to run level 5 (or whatever, It's just text, no graphics).
