Dear Dmitry,
We have ChimeraX 1.3 running smoothly with 3D graphics acceleration over VNC (TurboVNC server, any VNC client works in principle) sessions using VirtualGL:
Performance is quite good even when working from home connected to our university VPN.
Basically we launch ChimeraX using the command 'vglrun -d egl ChimeraX' (which you can easily put in an alias to 'ChimeraX').
The only minor issue we have currently is that for displaying EM maps, we have to give the map file already when opening ChimeraX (
'vglrun -d egl ChimeraX mymap.mrc' ), otherwise it doesn't work. But once you open a map you can open other maps from within the ChimeraX session. This is not an issue with PDB models.
I don't have much information about the setup because I didn't do it myself, but I can get more details from our cluster specialists if you are interested.
Best wishes,
