I have a NVIDIA GeForce GTX 580 graphics card and I installed Ubuntu 12.04 using the nomodeset
option. Now when I start the PC, in the login screen I can't move my mouse and then a black screen appears and the following message is repeated:
GPU lockup - switching to software fbcon
Failed to idle channel 1
PIPFO playlist Update failed
I know I have to install the NVIDIA drivers, but how can I access the terminal?
I tried Ctrl+Alt+F1, but it didn't work.
