Why are you making this more difficult than it needs to be? As I
already said, you don't need to use vglclient to display to a local X
proxy. Just do:
Xvfb :1 -screen 0 1024x768x24 -fbdir vfb_test/fbdir1 &
DISPLAY=:1 /opt/VirtualGL/bin/vglrun -c 0 +v -sp -fps 5.0
/opt/VirtualGL/bin/glxspheres
and similarly for display :2.
Not sure why the context would be indirect on display :0. When you log
into the server locally and run glxinfo, does it also report an indirect
context? If so, then it's probably something amiss with the driver
configuration. If, however, when you log into the server locally and
run glxinfo, it reports a direct context, then try leaving it logged in
and run VGL from your remote shell again. If you no longer get the
warning message, then that means there's something amiss with how
vglserver_config is configuring the device permissions on your machine.
It may be a bug in that script (it honestly doesn't get tested very
often on ATI hardware.)
