Public bug reported: There's already an upstream bug report here:
https://bugs.freedesktop.org/show_bug.cgi?id=99555 Basically, with Option "IndirectGLX" "True" and LIBGL_ALWAYS_INDIRECT=1 I get immediate crashes e.g. with glxgear: steved@xubuntu:~$ LIBGL_ALWAYS_INDIRECT=true glxgears Running synchronized to the vertical refresh. The framerate should be approximately the same as the monitor refresh rate. X Error of failed request: 255 Major opcode of failed request: 155 (GLX) Minor opcode of failed request: 1 (X_GLXRender) Serial number of failed request: 42 Current serial number in output stream: 936 I am trying to run what is effectively a traditional X Terminal, but as the hardware I am using has a 3D accelerated chipset it seems sensible to try to use it..
