That file is the only one that has today's date:

I guess the other files are from my experiments last week.

If you do start X from the commandline, you will get valuable stderr coming quite deep into the whole desktop startup process.

Does anyone know how to keep lightdm from starting during boot without using update-rc.d to delete the symlinks? Ubuntu does not have a multi-user command-line runlevel.
