[Octave-bug-tracker] [bug #44840] Plotting with Qt or FLTK from remote system fails

[Michael Godfrey]

Follow-up Comment #7, bug #44840 (project octave):

John,

Sure:

address@hidden ~]$ glxgears -info

^C
address@hidden ~]$ 
i.e. nothing.

I also tried under gdb:
Starting program: /usr/bin/glxgears 
[Thread debugging using libthread_db enabled]
Using host libthread_db library "/lib64/libthread_db.so.1".
^C
Program received signal SIGINT, Interrupt.
