Hello,

Here is the new set of reworked patches. I tested it quickly in a
vm with xfce and gnome (login, logout, switch user) and it seems ok.
I also attach a little scm file with a simple system definition with
lightdm and xfce for those willing to test it.
(also the password is "q" without quotes).

Have a nice day,
