Yes, it is.

I've also used 'startxfce4 --with-ck-launch' but as far

If you follow the source that resolves to
   ck-launch-session xfce4-session

-----

It's really common that as soon as you post a problem that you figure it 
out.  Examining the startx script, I see that running

$ startx -- vt7

moves the x11-display-device back to tty7 and the session is now active 
and all the poweroff, etc buttons are active.

If I change ~/.xinitrc to just have
   xfce4-session

it also works. It seems to inherit the session from login.

But a plain 'startxfce4' does not.  Another thing that does not work is 
not updating shadow or if the pam_ck_connector.so module in 
/etc/pam.d/system-session is not used.

The question now is how to address this in the book.  We may have to do 
it separately for each desktop environment.
