Thanks James, 
This is helpful, especially for debugging.

I'm looking through the Xorg.?.log files in /var/log/
Xorg.{0,2,3,4,5,9}.log
Xorg.{0,,2,3,4,5}.log.old

There is a lot there - but I'm not sure what I'm looking for.

Likewise, I'm looking through the files in /var/log/gdm for clues:
:0-greeter.log
:0-greeter.log.{1,2,3,4}
:0.log
:0.log.{1,2,3,4}
:0-slave.log
:0-slave.log.{1,2,3,4}
etc.
