Like GDM, SLiM looks for session types described by @file{.desktop} files and
allows users to choose a session from the log-in screen using @kbd{F1}. It
also honors @file{~/.xsession} files.
+
+Unlike GDM, SLiM does not spawn the user session on a different VT after
+logging in, which means that you can only start one graphical session. If you
+want to be able to run multiple graphical sessions at the same time you have
+to add multiple SLiM services to your system services. The following example
+shows how to replace the default GDM service with two SLiM services on tty7
+and tty8.
