Huh.  How odd.  I guess the next step would be to do "pgrep xf" on a
working and non-working system and see what's not running on the
non-working system.  (In particular, is xfce4-session running?)  Then
make sure the corresponding packages are installed on the non-working
system.

What display manager is the non-working system using?

Is /usr/bin/startxfce4 present on the non-working system?
