I changed the drivers for the GPU in ubuntu 12.04 because there were 4 available versions and I wanted to try them to fix the resolution problem, but when I restarted it now the computer wont start and it showing me the following options:
- ubuntu, with linux 3.5.0-32-generic
- ubuntu, with linux 3.5.0-32-generic (recovery mode)
- Previous linux versions
memory test (memtest86+)
memory test (memtest86+, serial console 115200)
or I can press 'c' for command line.
I assume I need to fix the drivers but I dont know how to do it with the command line
