[Octave-bug-tracker] [bug #43183] Insufficient GL support & segfault (cont.)

[Muhali]

Follow-up Comment #3, bug #43183 (project octave):

Sorry for not being clear enough. Yes, I see the behavior only for a ssh -X
connection, and then only if LIBGL_ALWAYS_INDIRECT is not set, in which case
glxinfo gives

Error: couldn't find RGB GLX visual or fbconfig
name of display: localhost:15.0

If set, glxinfo outputs
