Change resolution Ubuntu over Teamviewer

[Fredrik-s]

Hello,

Im running a computer with Ubuntu 14.04.1, no screen attached. I have installed Teamviewer 10.0.36897. Im trying to get it to produce fullscreen when connecting to it through Teamviewer, allthough it only shows 1024x768.


Before connecting to my "Ubuntu-computer" I have - under properties - added 1920x1200, like image below shows, allthough this doesn't help.


In Ubuntu under "Screens" the dropdown option to change resolution is grayed out, and Im not able to change there either.

How do I increase the resolution?
