<description summary="User idle time manager">
|
||||
This interface allows to monitor user idle time on a given seat. The interface
|
||||
allows to register timers which trigger after no user activity was registered
|
||||
on the seat for a given interval. It notifies when user activity resumes.
|
||||
|
||||
This is useful for applications wanting to perform actions when the user is not
|
||||
interacting with the system, e.g. chat applications setting the user as away, power
|
||||
management features to dim screen, etc..

|
||||
|
||||
# SYNOPSIS
|
||||
|
||||
*swayidle* [options] [events...]
|
||||
|
||||
# OPTIONS
|
||||
|
||||
*-h*

Show help message and quit.

|
||||
|
||||
# DESCRIPTION
|
||||
|
||||
swayidle listens for idle activity on your Wayland compositor and executes tasks
|
||||
on various idle-related events. You can specify any number of events at the
|
||||
command line.
|
||||
|
||||
# EVENTS
|
||||
|
||||
*timeout* <timeout> <timeout command> [resume <resume command>]
|
||||
Execute _timeout command_ if there is no activity for <timeout> seconds.
|
||||
|
||||
If you specify "resume <resume command>", _resume command_ will be run when
|
||||
there is activity again.
|
||||
|
||||
*before-sleep* <command>
|
||||
If built with systemd support, executes _command_ before systemd puts the
|
||||
computer to sleep.
|
||||
|
||||
All commands are executed in a shell.
|
||||
|
||||
# EXAMPLE
|
||||
|
||||
```
|
||||
swayidle \
|
||||
timeout 300 'swaylock -c 000000' \
|
||||
timeout 600 'swaymsg "output * dpms off"' \
|
||||
resume 'swaymsg "output * dpms on"' \
|
||||
before-sleep 'swaylock -c 000000'
|
||||
```
|
||||
|
||||
This will lock your screen after 300 seconds of inactivity, then turn off your
|
||||
displays after another 600 seconds, and turn your screens back on when resumed.
|
||||
It will also lock your screen before your computer goes to sleep.
