[winswitch] xpra and PyOpenGL

[Anthony Stone]

Hello,

I have just installed PyOpenGL-accelerate (I was using xpra without it
before) and I now get the error message below. xpra completes the
startup and is usable, but I would like to have OpenGL working. Is this
a known problem? Is it a bug or a problem with my setup? I have only
been using xpra for a few weeks so I'm not familiar with its workings.

I'm running xpra 1.04 under Ubuntu 16.04 to connect to a remote desktop
machine running the same version of xpra under Ubuntu 14.04.

Thanks,
Anthony
