How can I set guest OS screen resolution in virtualbox?

Question

I have installed virtual box on My ubuntu 14.04 machine and I have then installed ubuntu 14.04 in the VM as a guest OS as well.
I understand I need to correctly install virtualbox guest additions to enable the option to change screen resolution.
This may or may not have been successful, so now my question is:

assuming the guest additions installed successfully - how do I actually change the screen resolution?
i.e. do I

go into the system settings -> display and set from in there? or
do I go to the virtualbox application in the host OS, select preferences -> and set to hint or automatic?
does it just automatically set a sane screen resolution if you successfully install guest additions?

Run your virtual machine and open Terminal to execute:

sudo apt-get install virtualbox-guest-dkms virtualbox-guest-utils virtualbox-guest-x11

Restart your virtual machine: you will see the icons appearing in their natural dimensions (correct resolution)

@user4668401 You must run that on the guest OS – Jun 28 '15 at 09:34
tried it and it errors out: virtualbox-guest-x11 has unmet dependencies – the_velour_fog Jun 28 '15 at 10:22
