How to run programs in KDE after suspend wakeup

Question

How can i run programs after suspend wakeup in an X-Session (KDE)? Especially they are some scripts to set xinput properties, which are lost after suspend and need to be restored.

Answer 1

The prefereed way of doing this on an OS with systemd is by using /usr/lib/systemd/system-sleep/:

systemd runs all executables in /usr/lib/systemd/system-sleep/, passing two arguments to each of them:

Argument 1: either pre or post, depending on whether the machine is going to sleep or waking up Argument 2: suspend, hibernate or hybrid-sleep, depending on which is being invoked

In contrast to pm-utils, systemd will run these scripts concurrently and not one after another.

The output of any custom script will be logged by systemd-suspend.service, systemd-hibernate.service or systemd-hybrid-sleep.service. You can see its output in systemd's journal

An example script:

#!/bin/sh
case $1/$2 in
  pre/*)
    echo "Going to $2..."
    ;;
  post/*)
    echo "Waking up from $2..."
    ;;
esac
