Thanks, Jimmy. I missed that blog entry.
The second line tells the process which read the configuration file
which executable to invoke. In this case, it is a shell script
`unity-system-compositor.sleep` which simply sleeps a bit and then
invokes the `unity-system-compositor` executable. You can find them
both in /usr/sbin.
Only the first line (type=unity) need be commented out in order to
invoke X from LightDM without attempting Mir.
