I've just downloaded the missing xf86_glx package, and followed the instructions in 3Ddiag for implementing it (with a Voodoo3). However, when I try to run gears, I get the above message. The only reference I have been able to find is on the German SuSE mailing list, but the solution suggested there (run ldconfig) makes no difference. Does anyone have any idea of what I need to do to deal with the above error? Thanks Kevin
