[Octave-bug-tracker] [bug #44174] Remote X-Window display: command window blank, all other windows fine

[William Deninger]

Follow-up Comment #20, bug #44174 (project octave):

UBUNTU 14.04/16.04 resolution

I too had been having this octave command window problem using both Ubuntu
14.04 and 16.04: Octave works fine when launched from the console, but
remotely using Putty (with X forwarding) or ssh -X, the command window is
blank.  

I was able to resolve the problem comparing the shell environments (printenv)
from my ssh -X session (resulting in octave command window blank), and that
from my console (octave command window visible). 

The minimal environmental change that I required to get octave to function
under ssh -X (or Putty with X forwarding) on a Ubuntu 14.04 or 16.04 system
are below.  These changes may be added to the configuration script .bashrc,
but their impact on other X applications has not been evaluated.

export GTK_MODULES=gail:atk-bridge:unity-gtk-module
export GNOME_DESKTOP_SESSION_ID=this-is-depricated
