[Doc] turn off dpms on lock/turn on dpms on action about swaylock HOT 4 CLOSED

Sorry I just switched to sway recently. Would this script look like this:

# put task in background
swayidle \
    timeout 5 'swaymsg "output * dpms off"' \
    resume 'swaymsg "output * dpms on"' &
# lcok screen
swaylock -c000000
# kill last background task
kill %%

Or is there a better way to do this?

Here is another solution to this problem.

from swaylock.

trap is a shell builtin, it doesn't matter whether it's X11 or Wayland.

Though, xset dpms manages the timeout to enable DPMS. The Wayland equivalent would be swayidle.

We should document this in the README or elsewhere too

Not in the README, no. You can add this to the wiki though.

from swaylock.

A year later this is not in readme, and there is no wiki at all. Been trying for hours to get this to work, only now found this issue. Mind you Google also doesn't know any solutions. I say it's a good fit for readme as is a typical usecase. Or at least open the wiki.

@piu130's approach seems to be working, although also gives an error: Failed to find session name: PID 2957 does not belong to any known session.

Yet the trap command version doesn't integrate with swayidle. My purpose is to blank the screen immediately and then engage lock in 5 sec. So moving mouse too soon will cancel the locking also.
