The way it is expected to work is: XAUTHORITY is unset (i.e. points to
~/.Xauthority) and all keys are stored in ~/.Xauthority.  The `xauth'
command is used to add/remove keys to/from it.

Yes, most display managers do that to start the display, but when
someone logs in they also adds the display's key to the user's
~/.Xauthority file, so the XAUTHORITY var doesn't need to be set.
