Bug#875394: new install, gdm3 selected but alternatives/x-session-manager is Xfce

[Daniel Pocock]

Package: gdm3
Version: 3.22.3-3

During a new install of stretch (9.1.0), both GNOME and Xfce were selected

The popup appeared asking to choose a default display manager (gdm3 or
lightdm).  gdm3 was selected.

After installation, gdm3 appears, user logs in and sees the Xfce desktop

ls -l /etc/alternatives/x-session-manager

shows that it is using /usr/bin/startxfce4

Can the choice of display manager and session manager be combined, so if
the user chooses gdm3 they also get /usr/bin/gnome-session?


I changed this using:

$ sudo update-alternatives --config x-session-manager
