Ubuntu 12.10 Desktop does not shows when i installed ATI drivers!

[mayagrafix]

Ubuntu 12.10 Unity Desktop does not show after I installed propietary ATI drivers

I went to system settings > software sources > additional drivers and selected fglrx(proprietary) ATI drivers.

After installed I reboot and no Unity interface, very slow to move windows around desktop.

Able to open terminal and execute commands like firefox, which is how Im writing this.

How can I execute from a terminal system settings, then Software Sources, then additional drivers and revert to open source drivers?

or what is the best way to fix this?

Thanks for any and all help
