The Radeon driver is installed according to GREP (someone on LinuxQuestions.org suggested using 'dpkg -l | grep fglrx' to see if the modules were installed). I'm not the least bit familiar with the proper use (or any use!) of GREP, but it didn't give a location for the 3-4 modules it found, so it wasn't of much help. The same person had some other suggestions, but the Mint directory structure is different. I managed to get around that, but didn't know about piping to more or less (thanks Dr. Hu!! I needed that!!), which made manually searching directories difficult. I finally stumbled on the "find" command, which helped also. But I still haven't been able to restore video.
It shouldn't be so damned hard to remove a recalcitrant driver from the command line. I do understand that part of the difficulty is me being new to Linux, but help is hard to come by for newbies like me, especially with something like this. Instead of slipping my XP CD in though, I'm going to just do a fresh install of Mint. Won't be too hard to reconfigure, and only a few e-mail files will be lost for good. I tried booting from the CD and using the package manager, but that does no good... not that I thought it would.
Would be nice if there were a recovery mode that wouldn't delete all user files, but I'm not betting on it! THAT is something to put on the list!! XP will do a recovery install that just replaces OS files and leave the rest of the directory structure (and installed files, desktop, etc.) alone. Rarely fixes things, as XP is usually well munged up by the time someone tries to use it, but it should work well in Linux.
I'm not too disappointed that I'm having to reinstall everything to get the system back, was sort of expecting it.
I've also decided that the Radeon 9600 needs to go! The only other AGP card I have on hand is an ATI Rage 128 w/64MB, so I'm leaving the 9600 in for now. So I'm going to search the forum for a video card recommendation that will do 3D hardware acceleration. That might fix some Windows/Wine software problems...
