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.

I solved the problem forcing the GRUB to appear by pressing Shift repeatedly while starting the PC. Then I introduced nomodeset again and I followed this steps.
