my users exist on ldap and when they log on a machine I want them using gnome-session-flashback
what I've tried so far and hasn't worked
copy to skel a user folder after I made sure that user has gnome-session-flashback chosen by default ( choose flashback, enter, reboot, it has flashback prechosen )
this https://help.gnome.org/admin/system-admin-guide/stable/session-user.html.en
in ubuntu 16.04 I did this in /etc/lightdm/lightdm.conf user-session=gnome-flashback-metacity I haven't found an equivalent in gnome/ubuntu 18.04
