Public bug reported:
Impact
------
If an Ubuntu user installs gnome-shell, they will be shown a debconf prompt
asking to choose between gdm3 and lightdm. No information is given as to why
one or the other should be chosen.
This can be fixed by recommending gdm3 | lightdm
Test Case
---------
>From Ubuntu (Unity), install gnome-shell. gdm3 should not be installed and
>there should be no debconf prompt.
Regression Potential
--------------------
None really. GDM does look a bit nicer with GNOME Shell than LightDM in 17.04
and older releases but if a user wants GNOME Shell to look nice, they should
just install Ubuntu GNOME. It's not worth the avoidable debconf question for
that.
Other Info
----------
This was already done for artful as part of the GNOME transition.
Users will still see a debconf prompt if they install ubuntu-gnome-
desktop but there's not much we can do about that now in SRUs.
All Ubuntu "desktop" flavors except for Ubuntu GNOME and Kubuntu use
LightDM. Kubuntu currently uses sddm, but no one has bothered to get
sddm working with GNOME Shell.

If an Ubuntu user installs gnome-shell, they will be shown a debconf prompt

- This can be fixed by not having gnome-shell recommend gdm3 but letting
- the desktop metapackage take care of picking the Display Manager.
+ This can be fixed by recommending gdm3 | lightdm
Test Case
---------
From Ubuntu (Unity), install gnome-shell. gdm3 should not be installed and
there should be no debconf prompt.
Regression Potential
--------------------
- If a user installed from a minimal Ubuntu install and does not have any
-desktop package installed and their only desktop environment is gnome-shell,
then gdm3 may be marked as auto-removable. This scenario doesn't seem very
likely, and someone who is tweaking Ubuntu to that extent should know not to
auto-remove their display manager.
