[Octave-bug-tracker] [bug #51103] GUI command-line output window freezes after plot, but input still works

[Dan Sebald]

Follow-up Comment #14, bug #51103 (project octave):

I couldn't find any library file on my system with "mesa" name, so picked
this

LD_PRELOAD=/usr/lib/x86_64-linux-gnu/mesa/libGL.so.1.2.0

and that produces


libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
>> graphics_toolkit ('fltk')
>> plot ([1:50])
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast


at which point all of the GUI is frozen.  swrast is one of the OpenGL drivers
if I recall correctly (on its way out).

I configured osmesa out of the build.  (Of course, that doesn't mean it isn't
built into the program, just that it is apparently not used for drawing.)
