How to set gnome-classic as default session for all users in gdm3 (system-wide setting)? I'm using Debian Jessie with GNOME 3.12.

I've tried creating fake gnome.session in /etc/xdg/gnome-session/sessions that launches gnome-classic and searched for relevant gdm3 setting but to no avail. Solutions I've found online seem to work only for older GNOME versions.

This question came from our site for system and network administrators.

update-alternatives --install /etc/alternatives/x-session-manager \
  gnome-session-classic /usr/bin/gnome-session-classic 99

Should do the trick.

  • update-alternatives --install /usr/bin/x-session-manager x-session-manager /usr/bin/gnome-session-classic 90 – aleksandr barakin Apr 18 '17 at 12:48
  • @MasterM: Did either of these work for you? I'm using CentOS, so x-session-manager doesn't seem to apply for me, but was curious nonetheless. If it did, could you mark it as the accepted answer? – Randall Oct 3 at 15:48

I am using Debian Wheezy 7.8 with GNOME 3.4.2. After installing Debian and at the first user login, I could select gnome classic instead of system default login. After this selection and without any configuration, I am using the gnome classic exclusively.

  • Good for you. Now, how do you do it for all users at once, system-wide? – G-Man Says 'Reinstate Monica' Feb 22 '15 at 6:36
  • Go to /var/lib/AccountsService/users. For my case, I can see Debian-gdm file. It says [User] Language= XSession=. And I can see a file of my user name. It says [User] Language=en_US.utf8 XSession=gnome-fallback. Go to the following link [help.gnome.org/admin/system-admin-guide/stable/… – Juneil Feb 22 '15 at 7:13
  • (1) If you know an answer to the question, put it into your answer. Click on edit. (2) Provide a usable answer, not just a link. (3) If you know of link(s) that substantiate your answer and/or provide supplemental information, by all means include them in your answer. But verify them first; the URL you posted in your comment (above) doesn't work. – G-Man Says 'Reinstate Monica' Feb 22 '15 at 7:45
