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 http://support.amd.com/fr/gpudownload/linux/Pages/radeon_linux.aspx

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

Thank you!
