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.

Sorry. Enabling is almost the same set of steps: remove the

Another point from the same 2013-08-15 discussion, I'd still
prefer an enable=Y/N flag in the file mentioned below. It's just
much clearer in terms of intent. But, I'm okay with what we have.

One person (forgot who) was running with Mir for a bit and was
unhappy with the experience. This person did not want to go
through the bother of reinstalling their PC with something else +
catchup + customizations as they wanted to keep on trying the
preview of Xubuntu 13.10. Maybe someone else feels the same?
So, based on the collective conversation we had on 2013-08-15,
this will let you disable or re-enable Mir:
Disable:
1) Open a terminal window.
2) sudo /your-favorite-text-editor/
/etc/lightdm/lightdm.conf.d/10-unity-system-compositor.conf
3) On the line which reads, type=unity, insert an '#' in column
1, making the line a comment.
4) Save and exit.
5) sudo reboot
Enabling is almost the same set of steps (put the '#' back in
step 3).
The instructions on Jono's blog,
http://www.jonobacon.org/2013/08/15/mir-update-and-testing-mir-in-ubuntu-13-10/ , mention
two rows to comment:
================================
If you do have problems with Mir and want to start a normal X server,
simply edit
/etc/lightdm/lightdm.conf.d/10-unity-system-compositor.conf and
comment out the second and third lines:
[SeatDefaults]
#type=unity
#unity-compositor-command=unity-system-compositor.sleep
Now restart LightDM and you are good to go. Uncomment these lines to
go back to Mir.
================================
I don't know what the second line actually does or if they are
redundant once the type=unity is commented out?
