, 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?
