Problems with gdm but not with lightdm
In the same room :
- 13 PC Debian Buster with GDM (Gnome Display Manager)
- 8 old PC with Debian Buster with LightDM
The master is one of the 13
The master can see the 8 ones but none of the 12.
Could it be related with the display manager ?
(I've installed manually the latest version 4.5.6-0 : the oldest 4.1 used to be OK until some months (may be after an update of the Debian distribution)
