Figured out what the problem was. Bit of a do'h moment.
Haven't used Linux with X in years, so I blame it one rust.

I was expecting xbmc to run from CLI and it would start X itself.
It does not.
Running it inside startx does make it run.

Now I just have some tweaking to do.
Running a 10 bit video isn't as smooth as it was running OpenElec.
No hick ups, just slower every few seconds, then back to full speed.

Also, sound is running Analog instead of through HDMI, even though I only use HDMI.
Sounds plays back properly. Bit loud, so need to adjust that as well.
