Hi. I have an Ati Radeon X550 (512MB RAM) graphics card and, as you may or may not know, the official Ati drivers suck (in a metaphorical way). What I'm having most problems with is video: I can't get video acceleration for the life of me. Basically, xvimagesink doesn't work, only ximagesink does. Watching Flash videos on websites uses 100% CPU even though hardware acceleration is enabled in Flash (disabling it makes no difference whatsoever). Watching videos with slightly bigger resolution again uses 100% CPU and is choppy.
So, what I want to try, is to use the Ati community drivers. What I don't know is how to install / activate them. If I simply deactivate the official driver in System -> Administration -> Hardware Drivers? Or do I have to also install the community drivers afterwards?
