min install to graphical, sans gnome, how to start graphical.target

[Joel Rees]

Used the netinstall CD image on a USB stick to install the minimal
install -- F17 64 bit.

Boots to the text console.

yum groupinstalled Window Managers, X Window System, and Xfce.

/lib/systemd/system/default.target points to graphical.target .

/lib/systemd/system//graphical.target.wants contains
display.manager.service which is a link to
/usr/lib/systemd/system/display.manager.service .

I think I saw a message about gnome not being found at some point in
the boot process.

gdm is installed, for what it's worth, but man -k gdm doesn't tell me anything.

I can login to the text console and do

systemctl start graphical.target

and get the X11 login and login to the xfce desktop. Functions fine
from there. Reboot brings me back to the console login.

switchdesk xfce says it switched to xfce.

What do I need to look for? With all the earth moving under our feet
because of /usr merge and systemd, I have no idea where else needs to
be set up.
