[VirtualGL-Users] [VGL] ERROR: glXCreateContextAttribsARB symbol not loaded

[Alex Xu <ale...@ya...>]

I get the aforementioned error when running almost anything through
VirtualGL through various methods (SSH X11 forwarding and local VNC).

Specifically, running "vglconnect -s <host> <<< 'vglrun glxinfo'"
results in this error.

However, running "ssh <host> <<< 'DISPLAY=:0 glxinfo'" shows that
GLX_ARB_create_context is in fact provided by the graphics driver and
should be available.

Furthermore, running "vglconnect -s <host> <<< 'vglrun glxgears'" does
work (i.e. output to the connecting machine) and is much faster than
indirect rendering.

I tried Googling for it, but all I found was "update your graphics
drivers" and "use the proprietary drivers". I am using the latest
drivers, xf86-video-intel-2.99.217, and there are no proprietary drivers.

What troubleshooting steps could I take to narrow down the problem?
