Ubuntu – Problems loging in after dealing with video drivers and black screen

13.10driversdual-bootguinvidia

I recently installed Ubuntu 13.10 on my laptop alongside windows 8.1. I have a Nvidia GeForce GT 645M video card on it and was having black screen on boot issues. so I installed the xorg-edgers Nvidia drivers. After this fix I could get to the login screen, however whenever I would try to log in I get blank desktop screen with no interface and a warning saying "System program problem detected Do you want to report the problem now?" and If I log in as a guest I get a desktop screen with no interface.

Best Answer

If you can get to a Terminal prompt or Recovery Console,

sudo apt-get remove --purge nvidia-*

will remove the Nvidia drivers;

sudo rm /etc/X11/xorg.conf

will reset the X session settings; and

echo 'nouveau' | sudo tee -a /etc/modules

will load the default nouveau drivers to let you have a working GUI. A reboot may be required, or try service lightdm start to get to the login screen.
