Hey guys,

I'm new to Ubuntu, and inevitably I've run into problems. My GPU in particular.
I'm running a Radeon HD 6970, and I'm currently using the open-source drivers.

I've updated the Ubuntu and configured my secondary monitor, but the GUI, unity have begun lagging something unbearable. The GPU fan seems to run constantly at maximum even while idle.

Any ideas?

Thanks in advance for any help,

CGM.

P.S: Upon rebooting from upgrading to the proprietary drivers, unity and the entire GUI have disappeared.
