Okay thanks for the feedback. The knowledge base entry “https://www.nomachine.com/AR02L00782” is not very clear about server side graphics hardware utilisation. I’m not sure what it means by server side hardware acceleration?
I see that when we specify “lightweight” mode the rootless window seems to draw correctly. Can you select between vp8/h264/lightweight sessions as a client option? We require reasonable video playback across the LAN to clients machines so I suspect that NX compression is not going to as good as h264 for our purposes.
I managed to get the VGL stuff working by running startx as root so I suspect something isn’t working with gdm/kdm.
Cheers,
Daire
