I just see, that limbo goes back from gdm 2.32.0 to 2.20.11 - a step I won't go.
The new gdm is much more comfortabel, no unnecessary dialogue, when switching to another display manager - and you can easily switch between the accounts. And most notable - the background brought also the correct background for locked sessions, so not anymore the green leaf background when entering your password in a locked screen.
Is there a way to lock the package, that a step back is not possible, so protecting the actual installed gdm 2.32.0 package?
Thanks in advance,
