# Set how long before automatic lock.  We have the DPMS time and the
# automatic lock time set to the same value.
#
# I used to have have (e.g.) `xset s 150 180; xset dpms 1200 1200 0`
# with a --notifier option passed to xss-lock which used i3-nagbar to
# warn of an impending lock.  This warning was necessary because
# xtrlock's visual feedback is low.  However, when i3-nagbar (or,
# indeed, notify-send) is launched by xss-lock, they break the
# display of various windows until the mouse is moved around.  This
# problem does not occur if I launch i3-nagbar from a terminal window.
# In that case, everything gets redrawn as it should be.
#
# So instead, we wait to lock the screen until the point at which we
# are blanking it for power saving.  The screen going blank is
# sufficient visual feedback.
#
# If my screen actually needs locking, I always just do that manually,
# so this is only a fallback, in any case.
#
# Changes to these values should be kept in sync with comproc.org
# notes for configuring xfce4-power-manager
