I am using tightVNC to connect to an Ubuntu 18.04 server.

When I try to start blender, I get the following error in the command line:

Xlib: extension “XInputExtension” missing on display “:1”.
Read prefs: /home/shard1/.config/blender/2.79/config/userpref.blend
/build/blender-UBljLx/blender-2.79.b+dfsg0/intern/ghost/intern/GHOST_WindowX11.cpp:198: X11 glXQueryVersion() failed, verify working openGL system!
initial window could not find the GLX extension
Writing: /tmp/blender.crash.txt
Segmentation fault (core dumped)

I then tried to run sudo xinit & and /opt/VIrtualGL/bin/vglrun blender but got the following error:

Xlib: extension “XInputExtension” missing on display “:1”.
Read prefs: /home/shard1/.config/blender/2.79/config/userpref.blend
[VGL] ERROR: Could not open display :0.

I’m like 7 problems deep into the trouble shooting rabbit hole atm so any help would be greatly apreciated.
