I'm having problems with the ATI driver. It says that the system is not using the Proprietary Controller. I can't activate it and there aren't any suggestions on how to solve this.

I saw on another post an answer that recommends installing 'linux ati catalyst driver'from

Should I do that? Or is there a way around this.

Thank you!

As you can see from the ATI drivers Wiki you card is no longer supported by the ATI fglrx drivers, you can still use the open source available with Ubuntu.

I recommend that you remove the fglrx packages and remove your /etc/X11/xorg.conf file. That will revert to the open source drivers.
