-> The file '/tmp/.X0-lock' exists and appears to contain the process ID '1196' of a runnning X server.
ERROR: You appear to be running an X server; please exit X before installing.  For further details, 
please see the section INSTALLING THE NVIDIA DRIVER in the README available on the Linux driver download page at
ERROR: Installation has failed.  Please see the file '/var/log/nvidia-installer.log' for details.

how did you install the nvidia driver? from the nvidia website? – don.joey Feb 17 '13 at 18:43
install nvidia drivers through the "additional drivers" app in the dash. See here. Don't install them via nvidias website. – phipsalabim Feb 17 '13 at 19:26
I got an error after the install, no matter which driver i chose of the "additional drivers" app, but i managed to work it out. I followed the "guide" located here: – user132732 Feb 17 '13 at 19:41
