On Ubuntu 20.04, with gdm3 When my user succesfuly loggued-in, I've a pam-session script that do a lot of long running jobs before starting gnome. I simple looking for writing some basic info in the GDM UI to let know the user what's going on.
At the first login, I noticed "creating /home/users/myusersname directory" writted under the password field. It's done automaticaly, so it should be possible
Any Idea ?
Thanks in advance
