How can you have Octave-4 on Ubuntu 14 (which 14.04 or 14.10?)? Octave-4 is not provided or supported by Ubuntu 14.x? That said, running PTB in a Virtual Machine is pretty pointless, as the VM won't provide the timing precision and low level hardware access and graphics features that PTB needs to do much useful work.
The error messages don't make any sense, so i don't know - something is wrong. But the most easy way is to install ptb3 for Linux+Octave via the NeuroDebian repository, as recommended on our Downloads page. Setup there is as plug and play as it gets, so i'd try that.

Hello all,
I am a Mac and installed Ubuntu14, Octave4, and PTB3 on a VirtualMachine. I followed the Linux PTB installation instructions but when I do ScreenTest this is what I get:
After this happens I cannot exit Octave or do anything for that matter. It does not matter what I type I get the error:error: 'nargin' undefined near line 36 column 7
error: called from

ScreenTest at line 12 column 5
error: scope not found!
