[SOVLED] systemd's system-sleep hook doesn't run

I have some scripts that I want to run after coming out of suspend mode, so I've created some scripts in /lib/systemd/system-sleep, but they never run. Here's the inside of one of the scripts I stole from the internet:

/lib/systemd/system-sleep/debug:
#!/bin/sh
case $1/$2 in
  pre/*)
    echo "Going to $2..."
    # Place your pre suspend commands here, or `exit 0` if no pre suspend action required
    echo deez nutz > /home/sv-cheats-1/suspend
    ;;
  post/*)
    echo "Waking up from $2..."
    echo nutz deez > /home/sv-cheats-1/suspend
    # Place your post suspend (resume) commands here, or `exit 0` if no post suspend action required
    ;;
esac

Upon coming out of suspend there is no new text added to the text file via "echo", so I guess it doesn't work. Any ideas as to why and how to fix/debug this?

Re: [SOVLED] systemd's system-sleep hook doesn't run

I don't know why, but the below script seems to work as intended, don't know why the first one didn't work.

#!/bin/bash
case $1 in
pre) case $2 in
    hibernate)
            echo "Going to suspend to disk!"
            ;;
    hybrid-sleep)
            echo "Going to suspend to disk and ram!"
            ;;
    suspend)
            echo "Suspending to RAM." >> /home/sv-cheats-1/test
            /usr/bin/nmcli dev con enp5s0 >> /home/sv-cheats-1/test
            /usr/bin/warp-cli connect >> /home/sv-cheats-1/test
            ;;
    *)
            echo "Unexpected case"
            ;;
    esac ;;

post)
        echo "We are now resuming from $2."
        ;;
*)
        echo "Unexpected case"
        ;;
esac

Doesn't suggest that the script doesn't run - just that it fails?

/lib/systemd/system-sleep/debug:
#!/bin/bash
case $1/$2 in
  pre/*)
    echo "Going to $2..."
    # Place your pre suspend commands here, or `exit 0` if no pre suspend action required

Looks like it, seems like nmcli can't manage the device for some reason?

Re: [SOVLED] systemd's system-sleep hook doesn't run

I guess that's because of the S3 - what are you trying to do there itfp? Why are you trying to manipulate the network while entering the sleep?

I've setup warp vpn on my system and I've noticed that if I suspend the system the VPN disconnects. I had looked up and found a way to run script after coming out of suspend so I've setup that script. It worked for a while until one day it stopped working for some reason and would break the entire connection. I decided to add the

nmcli dev con enp5s0

to mediate that.

Re: [SOVLED] systemd's system-sleep hook doesn't run

Ok, so I've changed things so that they are where they should be:

#!/bin/bash
case $1 in
pre) case $2 in
    hibernate)
            echo "Going to suspend to disk!"
            ;;
    hybrid-sleep)
            echo "Going to suspend to disk and ram!"
            ;;
    suspend)
            echo "Suspending to RAM."
            ;;
    *)
            echo "Unexpected case"
            ;;
    esac ;;

post)
        echo "We are now resuming from $2."
        /usr/bin/nmcli dev con enp5s0 >> /home/sv-cheats-1/test
        /usr/bin/warp-cli connect >> /home/sv-cheats-1/test
        ;;
*)
        echo "Unexpected case"
        ;;
esac

Here's the output of "journalctl -b -u systemd-suspend.service"

May 01 22:38:24 sv-cheats-1 systemd-sleep[17371]: System returned from sleep state.
May 01 22:38:24 sv-cheats-1 systemd-sleep[17484]: We are now resuming from suspend.
May 01 22:38:24 sv-cheats-1 systemd-sleep[17491]: Error: Failed to add/activate new connection: Connection 'enp5s0' is not available on device enp5s0 because device is strictly unmanaged
May 01 22:38:24 sv-cheats-1 systemd[1]: systemd-suspend.service: Deactivated successfully.
May 01 22:38:24 sv-cheats-1 systemd[1]: Finished System Suspend.

The connection is still broken, still need to do things manually after resume.

This is probably running too early, https://wiki.archlinux.org/title/Networ … dispatcher ?
