Fedora doesn't have /etc/X11/Xsession.d, so this won't work on all
distributions. We need something reliable. Any other ideas? Uxlaunch
is no solution, especially not if it requires patching distro packages.

BTW, I asked on the ConsoleKit mailing list what we should do:

  http://lists.freedesktop.org/archives/consolekit/2010-September/000129.html

The reply I received was this: nothing. So we're neither supposed to
call ck-launch-session nor to open a new session ourselves in
xfce4-session. Still, this only works when using a login manager and a
Xorg startup method that sets CK session parameters like
x11-display properly...

A note to Enrico and Mike: if the underlying technologies change then
sometimes the way things work also changes. So if simply calling
"startxfce4" won't work anymore then that's fine, at least if there is
an alternative way with the new technologies.
