[PATCH] If neither HAL nor udev backends are enabled, warn the user

[Peter Hutterer]

If both are missing,  input device hotplugging will not work out of the box.
While we still have a DBus-API or the user may want to set AAD off all the
time, the most likely source of this is misconfiguration (i.e. lack of the
udev/hal devel packages).

Message printed last to make it more obvious to the user.
