Also, in my Xorg.0.log file, I have the errors:
(EE) Unable to locate/open config file: "/root/xorg.config.new"
(EE) open /dev/fb0: No such file or directory
(EE) Failed to initialize GLX extension (Compatible NVIDIA X driver not found)
The config file should be located at "/etc/X11/xorg.conf" though? Why would it be trying to look for a file in /root/? I don't know if this is significant, but thought it's worth a mention..
