# screen-lock (module screen-lock, novox/hq ADR 0208): the locker. xss-lock runs it on idle, before
|
|
# suspend and on logind's Lock, and node-lock-screen's `lock` ends in it.
|

#

|
# The operator's look, adopted from the predecessor's my-i3lock: the screen as it was, blurred, with
|
|
# an orange ring, the time and the date. That needs i3lock-color, from the distribution's user
|
|
# repository, kept as found until the mesh carries such software (novox/hq research 027, question 1).
|
|
# On a machine without it the distribution's i3lock shows the same blurred screen, taken here, with
|
|
# its own plain ring; failing that, black.
|
|
#
|
|
# Before a suspend, xss-lock hands this script a lock on the sleep (XSS_SLEEP_LOCK_FD) and suspends
|
|
# once it is released. The locker must not inherit it, or the machine would wait for the unlock
|
|
# before sleeping; it is released once i3lock is up, so the machine never sleeps unlocked. This is
|
|
# xss-lock's own documented pattern for i3lock.
