I have created a Ubuntu 14.04 VM on Virtualbox 4.3.16 (running on Windows 8). I have installed all of the Ubuntu virtualbox-guest* packages.
The highest screen resolution that I can set in the Ubuntu VM is 1280x960 (4:3). The other options are 1024x768 and 800x600. What I really want is to set the screen resolution to be identical to that of the host OS. ie. 1920x1080.
Does anyone know how to do this?
