I used ubuntu 12.04LTS. My Desktop can't start up after I installed the FGLRX from Additional Drivers in the System Setting menu. It stop at start-up purple screen. How can I fix this error?

  • Do you get a black screen?

You should be able to open any of the default Ubuntu text terminals by pressing:


where X in function key FX can be any number on your keyboard (for example, F4 or F5)

Have in mind, that function key F7 is reserved for the graphical terminal (where your FGLRX driver has crashed), thus you should use a different terminal.

Basically what you want is reconfigure xorg.conf (Xorg display server configuration file). You can do this by simply typing:

sudo rm /etc/X11/xorg.conf

After removing/reconfiguring the xorg.conf file, start the Xorg server with this command:

sudo startx
  • Thank you for your reply but I don't get a black screen. Nothing happen when I press Ctrl+Alt+FX (I tried X from 0 to 9). Commented Aug 30, 2014 at 11:20
  • Uhm, you then might try going into recovery mode, try this answer: askubuntu.com/a/120168/16981
