Bug#1006329: Acknowledgement (xwayland does not update dbus activation environment (DISPLAY, XAUTHORITY) on startup)

[Jameson Graef Rollins <jrollins@finestructure.net>]

I might be mischaracterizing this as an Xwayland issue.  Maybe it's a
sway issue?  The problem starts before Xwayland is in the picture,
before any X apps are launched.  waybar takes a long time to launch,
gpg-agent, pavucontrol, other things.  They all have these dbus
timeouts, that all seem to be fixed when I run the following command:

dbus-update-activation-environment DISPLAY XAUTHORITY

So maybe it's just the DISPLAY variable that's actually relevant?
Somehow that variable is defined by sway before Xwayland is ever
launched, but it's not communicated to my dbus session, since it's
started by systemd --user before I launch sway.
