Doing an upgrade to 15.04 doesn't work as expected.

[mpmc]

This is just a quick note to say that upgrading from 14.04 to 15.04 (14.04 -> 14.10 -> 15.04) does not work as expected, 14.04 -> 14.10 does work however.

It appears that something screws up during the upgrade, what that is I'm not sure. The system upgrades fine, I have no desktop & just a login prompt now, doing startx results in a load of messages mainly showing that xserver hasn't started at all/can't start.

So if you're tempted don't do it :p
