I've recently installed Ubuntu-x open source drivers for my ATI card on Ubuntu 12.04 LTS. I did it with the following commands:
sudo add-apt-repository ppa:ubuntu-x-swat/x-updates
sudo apt-get update
sudo apt-get install fglrx
And after running fglrxinfo, it returns the following:
$fglrxinfo
OpenGL vendor string: Advanced Micro Devices, Inc.
OpenGL renderer string: ATI Radeon HD 5670
My system still wasn't stable so I checked the 'Additional drivers' option and found out that the AMD/ATI proprietary drivers are activated. Does this mean I wasn't using the open source drivers at all? How can I make sure I'm using the open source drivers?
Help would be very much appreciated. Thanks!

is the closed source proprietary driver, refrain from installing it, if you want the open source one. – mikewhatever Aug 04 '12 at 12:49
