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.<br>
<br>
Only the first line (type=unity) need be commented out in order to
invoke X from LightDM without attempting Mir.<br>

<div>Sorry. Enabling is almost the same set of steps:
remove the existing '#' in step 3 is the only
difference. I must be getting old. Pity.<br>
<br>
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.<br>

So, based on the collective conversation we had on
2013-08-15, this will let you disable or re-enable
Mir:<br>
<br>
Disable:<br>
1) Open a terminal window.<br>
2) sudo <i>your-favorite-text-editor</i>
/etc/lightdm/lightdm.conf.d/10-unity-system-compositor.conf<br>
3) On the line which reads, type=unity, insert an '#'
in column 1, making the line a comment.<br>
4) Save and exit.<br>
5) sudo reboot<br>
<br>
Enabling is almost the same set of steps (put the '#'
back in step 3).<br>

two rows to comment:</div>
<div>================================</div>
<div>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:</div>
<div><br>
</div>
<div>[SeatDefaults]</div>
<div>#type=unity</div>
<div>#unity-compositor-command=unity-system-compositor.sleep</div>
<div>Now restart LightDM and you are good to go. Uncomment
these lines to go back to Mir. </div>
<div>================================</div>
<div><br>
</div>
<div>I don't know what the second line actually does or if
they are redundant once the type=unity is commented out?</div>
