PROGRAM:
NAME
glxheads - exercise multiple GLX connections
SYNOPSIS
glxheads [display ...]
DESCRIPTION
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.
EXAMPLE
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 following command-line:
$ glxheads :0 mars:0 venus:1
