http://ubuntuforums.org – Hello, I am trying to install Ubuntu 12.04.1 LTS or 11.10 (64bit versions). I have a Geforce 580GTX graphics card. When I just install the system normally and boot it up it will freeze almost instantly at the login screen. Sometimes I manage to push F2+Alt+Ctrl in time and can read "GPU Lockup - switching to software fbcon". I am aware this is a known problem and I have tried a lot of the suggested solutions. I tried removing the nouveau driver and installing the nvidia drivers by: sudo apt-get --purge remove xserver-xorg-video-nouveau sudo apt-get install linux-headers-`unam (Hardware)
