One more thing:

I can start the GDM manually by running

sudo gdm

and then selecting xfcesession. But I can't have it autostart now. I did
a check of systemctl status prefdm.service and was told:

prefdm.service
	  Loaded: error (Reason: No such file or directory)
	  Active: inactive (dead)

I also tried to do the symlink thing to make sure I was at the right
'runlevel' with systemd by typing

sudo ln -s /etc/systemd/system/default.target
/lib/systemd/system/graphical.target

and received:

ln: failed to create symbolic link
‘/lib/systemd/system/graphical.target’: File exists

This tells me everything *should* be fine. But it obviously isn't. Anyone?

Thanks!
