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!

fglrx is the closed-source driver!

Your steps in fact installed the AMD/ATI closed-source driver. The open-source one radeon is included by default with Ubuntu.

Please remove the fglrx drivers to "activate" the open-source one.

Not much help I know, but I had so many issues with ATi and Ubuntu, and Mint for that matter.

I had to reinstall my OS multiple times after messing things up by swapping drivers, etc.

I used the ATi drivers that are installed with Ubuntu, the drivers provided by Additional Drivers, and ATi's latest drivers on there website.

In the end I installed my Nvidia graphics card, and it worked instantly without issues.

Again, sorry it doesnt help, but if you have an Nvidia card laying about, my advice would be use that instead. Others will no doubt have better advice regarding your card and drivers I'm sure.
