I'm trying to run the example hello-world and don't get the window to
pop up. with standard display on my linux laptop:
*Main> :main
*** Exception: user error (Failed to create a window)
same with tightvncserver:
with Xvfb:
*Main> :main
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
*** Exception: user error (Failed to create a window)
... where Xvfb says:
$ Xvfb :2
