Bug#1054671: gdm not starting on boot

[Joey Hess]

Package: gdm3
Version: 45.0.1-1
Severity: normal

gdm was starting on boot until an upgrade a couple weeks ago. Now the
laptop boots to a getty, and I have to log in as root and 
systemctl start gdm3

There are no other login managers installed, although lightdm did get
installed breifly around the time this broke, and then removed.

Of course I've tried to enable the service, but:

root at darkstar:~>systemctl  enable gdm3
Synchronizing state of gdm3.service with SysV service script with /lib/systemd/systemd-sysv-install.
Executing: /lib/systemd/systemd-sysv-install enable gdm3
The unit files have no installation config (WantedBy=, RequiredBy=, UpheldBy=,
Also=, or Alias= settings in the [Install] section, and DefaultInstance= for
template units). This means they are not meant to be enabled or disabled using systemctl.

Possible reasons for having this kind of units are:
• A unit may be statically enabled by being symlinked from another unit's
  .wants/ or .requires/ directory.
• A unit's purpose may be to act as a helper for some other unit which has
  a requirement dependency on it.
• A unit may be started when needed via activation (socket, path, timer,
  D-Bus, udev, scripted systemctl call, ...).
• In case of template units, the unit is meant to be enabled with some
  instance name specified.

I don't see what other unit is supposed to depend on gdm3 and start it. I've
not been able to find any services like that on my system.

Note that I have task-gnome-desktop installed in full and am using gnome on wayland.
