Title:
Indirect GLX (LIBGL_ALWAYS_INDIRECT=1) causes opengl programms to
crash
Status in X.Org X server:
Confirmed
Status in xorg-server package in Ubuntu:
Confirmed
Bug description:
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..
