I upgraded to Ubuntu 12.04 because Gimp wouldn't install on 11.10. Said some conditions were not fulfilled. I upgraded and the graphics went for a toss. I was told by a friend to install the OpenGL drivers available on the nVIDIA website. I downloaded it and installed it then Ubuntu would not boot properly. Ubuntu always freezes up either at the login screen or the desktop. Sometimes it just hangs when I open the terminal. I reinstalled 11.10, again because I was told 12.04 had issues.
Now 11.10 will not load or has the same issues because of the graphic driver issues, I suppose. Now sometimes, on start up after the memory test, the screen just goes black with a blinking cursor on top. And I have no idea what to do with the Grub rescue. I am losing valuable time, unable to finish my work. I would appreciate it if someone could sort this out. Or atleast help me around with the grub rescue. How do I use that to fix the graphic issues?
My graphics card is a nVIDIA quadro fx 1500.
edit I have not yet installed the graphic drivers. The graphics were a little messed up when I had first installed ubuntu 11.10 but got worse after I updated it to 12.04. I re-installed 11.10 but the graphics are still as messed up. SO much so that I cannot even view the desktop if it finally does log me in.
