Hi Jan, Yes, preloading an incorrect version of the library will only give you more problems, that's the reason why I said to check the environmet variables. BUT in older versions of Ubuntu and with Mesa drivers there was a bug with the DRI drivers not linking to the libGL library see [1] and [2]. I have experienced the same error on ATI cards. Anyway I agree that it seems like a bad driver installation.
Cheers.
