I'm running Windows7 x64, Virtualbox 5.0.16 and just installed Ubuntu 14.04.
Ubuntu starts fine, but gives a very low resolution (e.g. 640x460).
I tried running sudo apt-get install virtualbox-guest-dkms virtualbox-guest-utils virtualbox-guest-x11
but this gives me the error
Unable to locate package virtualbox-guest-x11: depends on xorg-video abi-15 depends on xserver-xorg-core etc.etc.
I'm stuck here. Any suggestions (using newbie language?)
Thanks!
