Running Matlab 2014a under Ubuntu 14.04. Trying opengl('save', 'software') gives: OpenGL incorrect input argument: save
How do I set opengl to software by default fur future sessions?

I think that the "save" feature was added in R2014b. So you can't use it in R2014a.
The simplest workaround would probably be to edit your startup.m file and add a call to the opengl command to set it to what you want.

Ubuntu doesn't allow changing the opengl settings during the session.
Is there really no way to change the default settings in 2014a?

The R2014a documentation says,
"On UNIX systems, you must set the OpenGL version before MATLAB initializes OpenGL. Therefore, you cannot issue the opengl info command or create graphs before you call opengl software. To reenable hardware accelerated OpenGL, you must restart MATLAB."
So it is not generally true that you cannot change the opengl settings during the session: you just have to do it before you do graphics. Such as doing the change in startup.m
