Bug Description
Impact
======
A user who tries to use a different display manager than GDM might easily uninstall a package needed by GNOME Shell and therefore will be unable to log in to the default Ubuntu session or to GNOME or to GNOME Classic
Test Case
=========
Before applying the update
-------
sudo apt install lightdm
(Choose lightdm when asked which display manager to use)
sudo apt remove gdm3 gir1.2-gdm-1.0
(This will uninstall ubuntu-desktop.)
Reboot
Try to log in to Ubuntu
A black screen shows and you will get returned to the log in screen
The systemd journal shows this error:
gnome-shell: JS ERROR: Error: Requiring Gdm, version none: Typelib file for namespace 'Gdm' (any version) not found
After applying the update
-------
You won't be able to uninstall gir1.2-gdm-1.0 without uninstalling gnome-shell.
You should be able to log in to Ubuntu now from lightdm if gnome-shell and ubuntu-session are installed.
Regression Potential
=======
None. This simply restores a dependency that was accidentally not restored earlier. The dependency was dropped in
https:/
but ultimately it ended up being too difficult to run gnome-shell without gir1.2-gdm-1.0 installed so the Ubuntu Desktop Team decided to use GDM instead of LightDM plus the GDM gir by default.
