I've encountered a similar problem as Nvidia driver updated - mixed versions of 304.88 and 319.32 and Ubuntu 12.04 LTS - Black Screen at boot After changing Nvidia Driver

Using what I found there, I was able to purge the nvidia version 304 and reconfigure version 319. Now my problem is that I can get to the login screen for unity, but I can't get past this screen. I enter my password and I just here the drum sound and the login screen comes up again.


I had the same problem --> https://askubuntu.com/questions/351268/nvidia-driver-updated-mixed-versions-of-304-88-and-319-32-tried-saurav-kumar-f

but you only need to give ownership of Xorg back to your account as all the installs were done by root - that should solve your troubles.

simply boot into terminal (ctrl+alt+f3 in the login screen) login and write

sudo chown username:username .Xauthority

hope it helps

  • I couldn't get this to work with lightdm, kept looping me back to the login screen. I've switched to gdm and things are running fine. – Steele Sep 28 '13 at 21:44
  • if gdm is fine for you stay with it ;-) if not a remove/install lightdm might do the trick as well – Martin Lehmann Sep 28 '13 at 22:36
