Through a bit of trial and error I think I've got it working in both Direct and Raw modes.
Using vglclient: client> vglclient & client> ssh -X <server> server> export VGL_CLIENT=<client_ip>:0.0 server> vglrun -d :1 /opt/VirtualGL/bin/glxspheres64 This is on Ubuntu 18.04 which seems to create two displays when logged in on the server (one for gdm and one for the desktop). Using vncserver: server> /opt/TurboVNC/bin/vncserver Desktop 'TurboVNC: server:2 (dave)' started on display server:2 client> /opt/TurboVNC/bin/vncviewer server:2 & client> ssh server server> DISPLAY=:2 vglrun -d :1 /opt/VirtualGL/bin/glxspheres64 Polygons in scene: 62464 Visual ID of window: 0xad Context is Direct OpenGL Renderer: GeForce RTX 2080 App is rendering in the vnc window on the client so I think I'm good. Just to check,is it correct to use "ssh server" (no "-X") to hop to the server to launch applications (in this case)? Thanks, Dave.
