I have a HP Pavilion dv6 with Sandy Bridges Core-i7, dual-booted Win7 and Ubuntu 11.04. It also has a 1GB ATI Radeon 6490 discrete graphics card. In windows, the ATI utility works great and can switch between integrated and discrete graphics with no problem.
In Ubuntu, I have the proprietary ATI driver installed, but when I try to get to the Catlyst Control Center I get this error:
No ATI graphics driver is installed, or the ATI driver is not functioning properly. Please install the ATI driver appropriate for you ATI hardware, or configure using aticonfig.
I've looked at the aticonfig options, but can't really make sense of them, and there's only one ATI driver that I can find, so I don't know how I could have installed the wrong one.
In any case, I have given up on being able to use switchable graphics in Ubuntu (unless someone here knows a simple way to make it work), so I would like to set it up to only use the integrated graphics - I pretty much only use Linux for coding, so the discrete graphics are overkill and make my computer run hot and battery die quickly. Any help is greatly appreciated, I am fairly new to Linux in general.
