get back to ubuntu ATI video card install
I had ubuntu ( no dual boot ) on my laptop. With no hard to install driver problems. Decided to to install it also on the desktop( the real user machine ). I have dual monitor setup but with the default drivers i have split view, but no GPU acceleration. With the "suggested" drivers i had GPU acceleration but no split view, only mirror view. So how to fix this.
Install Ubuntu 13.04
Update software AND dont select any additional drivers.
Install ATI's official drivers ( download zip, unrar, execute .run file,
3.1 Download Arhive
3.3 chmod +x .run file
3.4 Run the script ( sudo ./*.run )
run in the terminal: amdcccle
Select your dual-split view settings, this will be only from the catalyst menu
