Octave gives the error unable to open X11 Display, when trying to plot graphs
When attempting to plot graphs in python 2.7 using matplotlib or Octave the program stalls and needs to be closed. Octave gives the following errors on startup:
No protocol specified octave: unable to open X11 DISPLAY octave: disabling GUI features No protocol specified
If I run plot(x,y) the program stalls and on pressing Ctrl-C the following appears.
gnuplot: unable to open display ':0' gnuplot: X11 aborted.
I have tried many online suggestions such as setting X11Forwarding to yes (which it already was), and running startx which leaves me with a blank screen with a cross cursor and changing DISPLAY to numerous things, among others.
UPDATE: When I run xinit I get the following:
(EE) Fatal server error: (EE) Server is already active for display 0 If this server is no longer running, remove /tmp/.X0-lock and start again. (EE) (EE) Please consult the The X.Org Foundation support at http://wiki.x.org for help. (EE) XIO: fatal IO error 11 (Resource temporarily unavailable) on X server ":0" after 7 requests (7 known processed) with 0 events remaining.
Not sure why I would need this or if it helps. Also in octave if I run 'setenv("DISPLAY")' then try to run a plot it still stalls but on canceling the terminal shows a blank screen with the forward, back and quit commands.
This is a new system and haven't had these problems with octave or python before.

So... you are running this remotely, via SSH? What is the local system? what X server is running on it? what SSH client are you using and is it configured for X11 forwarding (e.g.ssh -X)?

I'm running this locally on my machine, I'm not trying to use any ssh client. The xserver is xorg I believe. All I did was install octave as I normally would and on running this error occurs.

OK in that case I'm confused why X11Forwarding would come into the picture at all? You are not trying to run it as root (e.g.sudo octave) or from a CLI virtual terminal? is the display variable set in your session (echo $DISPLAY)? andoctavewas installed from the repository?
