[Octave-bug-tracker] [bug #44478] test __osmesa_print__.cc-tst crashes on Ubuntu with Nvidia drivers

[Andreas Weber]

Follow-up Comment #57, bug #44478 (project octave):

@Julien: Im able to use OSMesa with FLTK if I preload the mesa libGL.so. Can
you confirm that this also works for you?


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


my testscript:

graphics_toolkit fltk
figure ("visible", "off")
plot (1:10)
print ("-depsc", "out.eps")


This works with --no-gui, --no-gui-libs and the GUI with FLTK. When using Qt I
get


libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast
[xcb] Unknown sequence number while processing queue
[xcb] Most likely this is a multi-threaded client and XInitThreads has not
been called
[xcb] Aborting, sorry about that.
