I am running Ubuntu 12.04. A few hours ago, I started up my machine, checked my email, played a couple albums on Spotify and turned it off again. I did not notice anything out of the ordinary and I did not make any configuration changes. Just a few minutes ago, I turned it back on and:

  1. The computer posts
  2. The boot screen is showed and default boots to my Ubuntu install
  3. A screen with the multicolored background and the word "Ubuntu" shows for a split second
  4. A command line prompt appears

When I enter the startx command the following is outputted to the screen and then the computer stalls (no gui and no command prompt):

I tried commenting out line 13 of fstab, but that didn't make a difference.

I dual boot with a Windows 7 install, but have not booted that for a few days. I have an AMD graphics card that uses the proprietary drivers.

I saw this post but a comment on the post said the post was dead and if you have similar issues, post a new question.

  • I couldn't find a way to comment on your answer, but how did you re-install your Graphics driver. I'm seeing the same thing with Windows 8 and Ubuntu 13.04 after setting up the AMD driver. How did you re-install if if you can't boot the machine into Ubuntu? – bmcgonag Jun 14 '13 at 2:55
  • @bmcgonag I had to reinstall it from the command line. I followed the instructions on this page, under "Installing Catalyst Manually". There is a guide for 13.04 here. Make sure to follow the instructions for removing the current driver first. – bwroga Jun 14 '13 at 12:52

I think the problem was with my graphics driver. I reinstalled it and everything is working now.
