Comment 56 for bug 203158

mattrenfer, I've had some success with the ATI proprietary drivers so I think it would be worth a try for you. It appears your particular card only has legacy support so if the driver doesn't work very well for you you'd better go back to the open source one because there will not be any updates/upgrades. The driver should appear in System/Administrative/Hardware Drivers (if not then it can be downloaded here: http://support.amd.com/us/gpudownload/Pages/index.aspx Search the Ubuntu wiki for installation instructions).
