I was wrong about ssh working. The whole machine locks up when X starts.

A strange thing, sometimes I can log in from lightdm before it locks up,
sometimes I cannot even use the login screen. Timing related?

If I don't start X, console login seems to work fine, and I see nothing
obvious in the logs or kernel messages.

I will try to start just a window manager with startx instead of going
through lightdm.
