Hello,
I need to detect within a C++ program whether or not I'm running under
VirtualGL, to enable certain optimizations. What is the recommended way to do
this?
Cheers,
Stefan.

An easy way to verify
whether VirtualGL is engaged is to set VGL_LOGO=1 in the environment.
This will display a "VGL" logo in the bottom right of the OpenGL
rendering area if VGL is active.

It's not documented, but you could leverage the auto

When VGL is running it overrides the GLX vendor strings with
"VirtualGL". Try glXGetClie

That wouldn't work, because I need this information to build my (multi-GPU)
configuration.

I just heard back today about testing with GLX_STENCIL_SIZE,8. The
patch is it is working fine, but bad news is, the
