xbmc no render

I’ve installed opensuse 12.1
I have an error to get XBMC to run, despite I installed official ATI drivers, on OpenSUSE 12.1 XBMC tell me that “Needs hardware accelerated OpenGL renderring” …

Someone can help me please?
Many thanks and sorry for my english!

Make sure the ATI proprietary driver is active - it may have installed but failed to compile or run. The wiki and tutorials have some instructions on that.
