Mike

I have uninstalled the nvidia driver (304).


./run-octave -g --no-gui

The origin of fault comes from the nvidia driver.

I am using the Ubuntu 14.04 on GNOME desktop but not Unity.
The unity desktop does not work for my PC with and without the nvidia driver.

I will use my Ubuntu PC without the nvidia driver at the moment.

Thank you for your advise.
