Wow, worked on this 2 days before I submit a bug report, and then solve it 5 minutes later...

For anyone else in a simular situation here is what I found:

The "Command Window" looks like it ties into OpenGL somewhere along the line (probably through Qt). On a VirtualBox'ified Ubuntu, you need to make sure that Virtual Box's Video 3D Acceleration is turned on, re-install GuestAdditions (to make sure it grabs all the GL virtualbox tie-in drivers) and reboot (to easily make sure it all gets loaded).

After I did this my command Window text appeared :)

(Also I tried running octave as root [I know bad idea], from the directory I built it in using the "./run-octave" script, and it also failed to show the command window text. I also found that if I ran octave as root after I ran that script it still failed to show text in command window, but once I switched back to my normal user account it worked fine again)

Thanks Anyway :) Hopefully this helps anyone else

Greetings,

I built octave-4.0.0 from source on Virtualized (in VirtualBox) Ubuntu 14.04.3 LTS using tarbal:

and installed dependencies:

After the ./configure, make, make install (i've also rebuilt several times and used make -j4, rather than just make). I keep getting the same error where when I try typing text in the GUI "command Window" no text appears. The cursor is there blinking at the first row and column, but no text.

It seems my input is being processed since I tried creating a simple variable and plotting it, and the correct plot appeared. I also see my text appear in the command history window (after I press enter of course in the Command Window), so I know it is interpreting my text.

The reason I need the Command Window to work is because I get no error or feedback information after trying to run a command.

Has anyone experienced this? I found one thread of a guy saying he apt-get installed octave-strings, but when I try this, apt wants to also install an older version of octave. I tried installing the source package by hand, but got lost after I untar'd the package.

Any help is much appreciated! Thank you in advance!
-Nate
