Simon, I noticed you're using VirtualBox as well... Might it have something to do with it? The last time it happened to me it was running... Anyway, have you managed to make any progress on this?

Sometimes my X "partially freezes" like my mouse is working, but I can't click on anything on the screen. I'm running on a laptop and I have a second screen using laptop displayport. It happens very often since I switched to Ubuntu 14.04. On 13.10 sometimes my X crashed but few times only and it was related to LibreOffice only (at first glance...)
