A while back, I installed Backtrack 5 R2 to Dual Boot on a Windows 7 PC. It worked fine for a while, but now when I try to load it, the screen gets all messed up (tried to get a picture with my phone, but it wasn't working too well). The last line before it freezes says:
fb: conflicting fb hw usage: nouveaufb vs VESA VGA - removing generic driver
Since it last worked, the only changes I can think of are that the computer is now connected via the ethernet cable to the router, and I upgraded the graphics card (to Nvidia). Because of the last line, I personally would put my money on the latter, but I still have no clue how to fix this. Can someone help me?
