here's some more relevant info:
Ubuntu 14.04
libgl1-mesa-dri=10.1.3-0ubuntu0.4 (provides i915 Intel driver)
libgl1-mesa-glx=10.1.3-0ubuntu0.4 (provides
/usr/lib/x86_64-linux-gnu/mesa/libGL.so.1.2.0)
libgl1-mesa-dev=10.1.3-0ubuntu0.4 (provides symlink to the above in
/usr/lib/x86_64-linux-gnu/libGL.so)
nvidia-346=346.82-0ubuntu0.2 (provides Nvidia driver)
bumblebee=3.2.1-93 (provides optirun and /etc/bumblebee/bumblebee.conf)
this is just for reference, but if someone would let me know what exactly multi
sampling does to instancing a GraphicsContext that it Sigfaults when used with
"virtualgl", i would appreciate it.
p.s: compile example with: "g++ multisample.cpp -losg -losgViewer -g -o
multisampletest"
Thanks
Hamza
