Follow-up Comment #19, bug #44174 (project octave):
Michael, I think I may have found a workaround:
I had a similar experience this week after upgrading from Fedora 19 to Fedora
23 and also re-compiling Octave.
The gui window will open, but as soon as I try to run anything that opens a
figure() window, everything hangs and the octave gui goes blank and
unresponsive.
After much trouble I found out that the problem was related to the ssh
X11Forwarding mechanism, which I was using for the login into the machine
where I started octave (which was actually localhost, but I was using ssh -X
anyway).
Workaround: If I invoke octave with
env DISPLAY=:0 octave
rather than allowing it to run with the DISPLAY=localhost:11 tunnel that ssh
-X creates, then the problem goes away.
I have not been able to find what was wrong with /etc/ssh/ssh_conf. I tried
multiple variations (yes/no) of
ForwardX11 yes
Tunnel yes
with no luck. Not even sure if Tunnel is relevant. Also tried ssh -Y (not -X)
with setting "ForwardX11Trusted yes" is ssh_config. No luck.
