I recently upgraded my graphics card by buying and installing an AMD Radeon HD 6570. My Windows partition works fine, but my OpenSUSE 12.1 Linux partition is having a strange issue.
When I try to boot into SUSE it appears to load fine at first, giving me the green screen with the OpenSUSE name and the chameleon.
However, right around the time the chameleon's eyes would move, the screen switches to what I can only describe as green and black bars. It loads this way for a while then switches to blue and black bars, which I assume is the login screen.
I had been using LXDE before, and it was working fine before I switched GPUs. Is there any way for me to fix this, or should I try a different Linux distro? If the latter, is Lubuntu compatible with my GPU?
Also, I've tried using Ctrl+Alt+F2 (I believe that's the correct combo, haven't been able to use Linux in almost a month) to get to a command line but that won't work either.
