Both

  nvidia-340 (recommended)
  Version 340.96-0ubuntu0.14.04.1
  NVIDIA binary driver - version 340.96

and

  xserver-xorg-video-nouveau (open-source)
  Version 1:1.0.10-1ubuntu2
  X.Org X server - Nouveau display driver

work with the above set of commands when launching the GUI, and the 
former works for

  run-octave --no-gui
  run-octave --no-window-system

But the documentation still fails with an "octave exited with signal 11" 
error message.  There could be multi issues here.  I'll try isolating 
the documentation build issue.
