glxheads - exercise multiple GLX connections
glxheads [display ...]
The glxheads program will try to open GLX connections on multiple X
displays as specified on the command-line. If a connection can be made
it will try to create a direct GLX context (and fallback to using
indirect contexts if that fails) and open a window displaying a
spinning green triangle.
If no display names are specified, glxheads will default to opening a
single local connection on display 0.
To open a local connection on display 0 and two remote connections to
the hosts mars (display 0) and venus (display 1), run glxheads with the
$ glxheads :0 mars:0 venus:1
