Hi, Several people have noticed this OpenGL error when upgrading from Wine 0.9.19 to 0.9.20: X Error of failed request: GLXUnsupportedPrivateRequest Major opcode of failed request: 143 (GLX) Minor opcode of failed request: 17 (X_GLXVendorPrivateWithReply) Serial number of failed request: 384 Current serial number in output stream: 384 The program then exits. http://www.mail-archive.com/wine-devel@winehq.org/msg30150.html This is just a short notice that it also happened to me using Supreme Snowboarding (full German version). If requested, I can produce log files. I'm using Debian Ubuntu Dapper on a laptop with Xorg 7.0, libgl-mesa-6.4.1 on an Intel i810 chip. Configuring Supreme in "Software2" 3D emulation mode instead of "OpenGL", the program's window comes up. So it is related to OpenGL and the transition from 0.9.19 to 0.9.20. (In case you're wondering, I still can't play Supreme Snowboarding in Wine, the program freezes when entering race or training mode, but that's another topic). Regards, Jorg Hohle
