Comment 23 for bug 1562219

Me too. Under 16.04, 64 bit, with openbox, startx (or xinit) as user fails. Sudo startx gives me a console with a tiny font, so apparently it starts X but not Openbox. I'd explore that further and probably find how to start Openbox, but I don't want to run X as root anyway. I just tried sudo as a diagnostic experiment.

I have another 16.04 64 bit system on the same machine using lighdm. That does boot and run openbox. That sys has OTHER problems I won't go into here, but it does prove the problem lies with xinit. Given all the OTHER problems with it, it also proves that 16.04 wasn't ready for release at all, let alone as an LTS. Maybe Canonical needs to reconsider the release-on-schedule policy and instead wait until they get through the alpha stage.
