Describe the shipped labwc-session.target in labwc(1) SESSION MANAGEMENT
and add commented-out systemctl start/stop lines to the example
autostart and shutdown files. Users on systemd-based distros can
uncomment these to pull in graphical-session.target when labwc starts
and tear it down cleanly on exit, without labwc itself mandating any
specific init system.
swayidle previously used wlr-randr to enable/disable outputs, but since
commit a837fefc, this re-arranges views so is not to be used in the
context of idle system power management.
