If the :0 X server is idle, that means (for whatever reason) the commands aren't ever making it there.I've disabled GLX support in Xvnc now, but the problem is the same. Xvnc CPU usage is very high. I'll continue debugging...
I believe I've found the problem: Xvnc:s -DeferUpdate mechanism. It is known to be problematic current TigerVNC versions. I got these results:
DeferUpdate frames/sec ======================= 1 11 10 20 20 37 30 50 40 56 50 68 60 76 70 79 80 86 90 95 100 96OTOH, I'm not sure it really matters: the important thing is how many frames that are actually delivered to the VNC client; not how many frames the application can render on the server.
