To follow up on my own mail: I forgot to mention that there is a way to get the previous behaviour of gdm back: In /etc/X11/gdm/gdm.conf set ShowLastSession=true which will give an additional entry "Last" in the session menu, giving the user a way to get back to the choice of his last session. the comments say: # Normally there is a session type called 'Last' that is shown which refers to # the last session the user used. If off, we will be in 'switchdesk' mode where # the session saving stuff is disabled in GDM Fedora's default is ShowLastSession=false, so the "Last" choice isn't there, and gdm doesn't save your selection for next time, depending on (the totally broken behaviour of) switchdesk.
