I was trying to make the switch possible between my Intel and Radeon AMD graphic card following this thread: http://ubuntuforums.org/showthread.php?t=1930450, but apparently the installation of the packages messed up my default configuration (yeah, my graphic cards weren't in the list of "supported"...but I wanted to check anyways!), which caused compiz to crash and I don't know how to restore the default configuration so compiz will work again.

I was at Step 1, in the part when it says:

and configure the Xserver (xorg.conf file) for the first time:

sudo aticonfig --initial -f

After that, I rebooted and everything crashed. Is there a way to go back? Thanks in advance.

  • Processor: i7-2670QM.
  • Graphic cards: AMD Radeon HD 6600M Series and a 2nd Generation Core Processor Family Integrated Graphics Controller. I
  • I'm running on Ubuntu 12.10.

Thanks in advance.

Manually installing fglrx ruins your OS. tsk tsk. May as well wipe and reinstall. You can try deleting xorg.conf, purging all fglrx, and undoing all edits. –  Bryce Jan 6 '13 at 5:49
    
What I finally did was to re-install Ubuntu :-(. –  Néstor Jan 6 '13 at 20:44
