heads up about f18+ and lid/power buttons

[Raphael Groner]

Hi,

as it seems, Fedora has several other issues with systemd's inhibit.

system hibernation should be prohibited after kernel update
https://bugzilla.redhat.com/show_bug.cgi?id=843014

Systemd service should inhibit suspend while remote users are logged in
via ssh
https://bugzilla.redhat.com/show_bug.cgi?id=837109

Maybe it's better to disable systemd power management for the Xfce
spin, till all that issues are fixed for sure.

-R.
