Hi Ricardo, I checked and implemented your suggested solution on my system and it doesn't work. Actually, a more detailed configuration may be needed, see:
https://unix.stackexchange.com/questions/317954/x-forwarding-with-indirect-rendering-fails-with-newer-clients Although I have my X server running with the +iglx switch, openGL apps (e.g. pyMOL) still fail with error "Xlib: extension "GLX" missing on display ":1.0"." For me, vglrun is the best solution.
