Switching between open source and proprietary graphic drivers

Asked by Geoff Smith

Is there a way of switching between the Open source driver for Gnome 3 and the Proprietary driver for Unity? At present I am forced to use the default driver for both Gnome 3 and Unity as the ATI Proprietary driver causes distorted graphics in Gnome 3 - See my original question for a background on my problem -


Can this be achieved without rebooting?
Thank you,
Geoff Smith

Hi Sam,
Thanks for your quick response - please excuse my ignorance but isn't the fallback default driver the ATI driver?
I could see there were some pieces of fglrx left in my system which I will get rid of. At present I operate both Unity and Gnome 3 (my preference) without issues after I did a fresh install. I was under the impression that the fglrx driver would eventually have it's problems rectified - Is this not so? I am confused regarding whether the default driver is the ATI driver. Does the ATI driver need to be installed? Sorry to drag out the issue.

The only reference to fglrx that I found were in the following -
Am I right in assuming that these entries are normal and don't need to be purged as per the Wiki? Or do I need to follow the purging commands?
As I previously indicated, both Gnome 3 and Unity are working without apparent issues - I now think I understand that the default driver is in fact the ATI or Radeon Driver.
I apologize for dragging out this question -

The switch can be done via 'additional drivers' in gnome-control-center aka system settings and needs a reboot.
According to Wiki interference is a known issue, if all runs well mentioned entries in #3 don't need to be purged.
And yes, ati or radeon are default.

Can you help with this problem?
