I disagree that this is invalid.

From the release notes for Ubuntu 14.04.02: "Anyone wishing to opt into the hardware enablement stack for Trusty may do so by running following command which will install the linux-generic-lts-utopic and xserver-xorg-lts-utopic packages:

sudo apt-get install linux-generic-lts-utopic xserver-xorg-lts-utopic libegl1-mesa-drivers-lts-utopic xserver-xorg-video-all-lts-utopic xserver-xorg-input-all-lts-utopic "

If you already have Ubuntu 14.04.01 installed in Virtualbox with guest additions running, this will result in virtualbox-guest-x11 being removed and it is impossible to reinstall due to the unmet dependencies listed above.

This is not about mixing an xorg from Utopic. It's about updating your LTS release and that update breaking a fairly important piece of functionality. Basically without the guest-x11 package, virtualbox defaults to 640x480 resolution and become basically useless.
