Had the same problem on Quantal Quetzal (beta, x86_64). DRI modules would not load. In my case it was r600_dri.so
I found the modules in: /usr/lib/x86_64-linux-gnu/dri That directory is not on the path searched by libgl when it tries to load the modules. I solved it by symlinking: ln -s /usr/lib/x86_64-linux-gnu/dri/r600_dri.so /usr/lib/dri/ -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to mesa in Ubuntu. https://bugs.launchpad.net/bugs/47793 Title: DRI module load fails (undefined symbol: _glapi_Dispatch) Status in “mesa” package in Ubuntu: Invalid Status in “vmware-player” package in Ubuntu: Invalid Status in “xserver-xorg-video-i810” package in Ubuntu: Invalid Bug description: Binary package hint: vmware-player I have found a bug in vmware player in Ubuntu Dapper (also applies to vmware workstation trial). With a guest configured to use accelerated 3D (mks.enable3d = TRUE set in machine's .vmx configuration), the following error is reported in a window before the guest machine boots: "Direct rendering is not available. Failed to construct 3-D rendering backend. The 3-D features of the display card will be disabled".

Notes: 1. glxinfo reports direct rendering as enabled, and all other opengl applications work without this issue. 2. I came across this issue with the emulator "epsxe" (same degub output, "undefined symbol: _glapi_Dispatch", workaround was: "LD_PRELOAD=/usr/lib/libGL.so.1 epsxe" which enabled 3D acceleration. This was not successful with vmplayer/vmware workstation. 3. VMWare Tools is installed and configured correctly on the Windows XP guest. When running VMWare Workstation using Windows as the host, acceleration works on the guest machine perfectly.
