Is it possible to render image in vnc environment?

[zhengwx11]

by running ~/lab$ bazel run :random_agent --define headless=false, a graphic interface is obtained when I use physical screen, mouse and keyboard.

Is there any way to run it under vnc viewer?
I've tried but got a 'GlxBadRenderRequest'.

I had similar issues See #22 (comment)

I tried building deepmind lab and running it. I'm doing it on vnc window. When I run 'bazel run :game --define headless=false -- --level_script tests/demo_map' I see a window pop up saying 'GLimp_Init()-could not load OpenGL subsystem. See "/home/ckim/.deepmind_lab/baselab/crashlog.txt" for details.' Has it something to do with vnc? I searched the web but couldn't figure out yet.
ADD : this morning, after a long break, I'm back at work and tried the same command 'bazel run :random_agent --define headless=false -- --length=10000 --width=640 --height=480' with real monitor (not using vnc) above and it works. (It didn't work with vnc before).

@chankim: The headless=false build probably requires OpenGL, which may not work via VNC. Try the headless=osmesa build (or rebuild your SDL library with osmesa?).

Ok, Thank you for the information.

I assume this is settled? Please reopen if not.
