If you want to be sure you're using Xfce, try using startxfce4
instead.
Joe, thanks for that "startxfce4", it completely changed what i was getting
for the graphical display, now clearly in XFCE.
So that is a big advance for me.
I am still stuck on the reboot forcing me to go to console and "startxfce4".
The boot process looks really barren, with a single blue-white bar
with "fedora 16" in blue at far right,
at the bottom of a black screen.
Possibly this problem caused by cruft from the preupgrade,
run from f14, which itself is a preupgrade from f12.
Or, I did something weird during the preupgrade.
