My main computer is running Ubuntu 14.04.4 LTS, and I’m currently waiting for the Ubuntu 16.04.1 before upgrading to the latest version, which should happen in July. In the meantime, I have upgraded one of my VirtualBox image from Ubuntu 14.04 to Ubuntu 16.04, but I had only two options to set the resolution: 1024×768 or 800×600. This is quite a common problem, and usually the solution is to install VirtualBox additions, but this would not do for me.
After trying several solutions, including disabling 3D graphics support, without success, I decided to check Additional Drivers, and I noticed only VirtualBox Graphics Adapter driver was enabled. So I also enabled Innotek Systemberatubg GmbH: VirtualBox Guest Service, and Processor microcode firmware for AMD CPUs, and this fixed the issues most likely thanks to the former.
I’m running VirtualBox 5.0.18 installed from the ppa.

My virtualbox instance used to work with this when I installed from pre-release iso, but after update to the final release it got broken. In my case manually installing the extensions from Virutalbox’s fake cdrom helped some – screen resizing started to work again, but with several seconds of lag, while prior to the update that was near-instant.
