Yes. Although I dont think installing both VirtualGL + TurboVNC offer
much/any advantage. TurboVNC by itself with libjpeg-turbo compression is
prob the reason I would use over other VNCs.
The roundabout way is: Set the environment variable LIBGL_ALWAYS_INDIRECT to
"yes" in the shell you run the graphics application from.
The permanent way is: On linux, you need replace mesa-glx with mesa-swx, on
Ubuntu thats 'libgl1-mesa-swx' package which replaces 'libgl1-mesa-glx'.
I dont really understand mesa fully yet, but mesa-glx will try to render on
hardware and if it doesnt find any then indirectly to software, or not at
all in some cases. It didnt find any 3d hardware so it went indirect in your
case.
Install the swx and glxinfo will show to "direct rendering: yes". Your
opengl app should run normally in TurboVNC (without invoking vglrun)
