[Octave-bug-tracker] [bug #44467] libGL error: failed to load driver: swrast

[ederag]

Follow-up Comment #2, bug #44467 (project octave):

Thanks for your reply.
Both glxinfo, glxgears work as expected
LIBGL_DEBUG=verbose glxgears
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
302 frames in 5.0 seconds = 60.263 FPS

while after running octave (with or without --no-gui)
LIBGL_DEBUG=verbose ./run-octave
plot(1:10)
libGL: screen 0 does not appear to be DRI3 capable
libGL: screen 0 does not appear to be DRI2 capable
libGL: OpenDriver: trying /usr/lib64/dri/tls/swrast_dri.so
libGL: OpenDriver: trying /usr/lib64/dri/swrast_dri.so
libGL: Can't open configuration file /home/<user>/.drirc: No such file or
directory.
libGL: Can't open configuration file /home/<user>/.drirc: No such file or
directory.
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast

Forcing the wrong library path before running glxgears yield the same error:
LD_LIBRARY_PATH=/usr/lib64/:$LD_LIBRARY_PATH glxgears
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
Running synchronized to the vertical refresh.  The framerate should be
approximately the same as the monitor refresh rate.
363 frames in 5.3 seconds = 68.253 FPS
Side note: while the refresh rate is about the same, in this case, the
animation is jerky.
