a command to be executed during shutdown

[littleblack111]

Description

like a command that executes before anything start to shutdown.

use cases of this can be for sth like: #2475 (comment)
or stuff like writing script to see if system is updating and cancel the shutdown if it is

[Aqa-Ib]

You can script this with a systemd unit targetting shutdown.target. Ask chatgpt.

Not a hyprland issue.

[littleblack111]

ik. i mean this isnt really a issue... its a feature request

but if i do before shutdown.target
it would be like display manger closed, pipwire and everything.

thus stuff like #2475 (comment) won't be achivable

[Aqa-Ib]

Still a systemd thing. You need a hyprland.service started by systemd and a script.service that triggers After=hyprland.service

[littleblack111]

uncertain wdym by a hyprland.service. but if its a service that runs along hyprland or starts hyprland. then i'm pretty sure After=hyprland will make it start after hyprland start instead of when hyprland is shutting down. but even if it runs after hyprland shuts. still wont be able to do stuff like #2475 (comment) cuz

it would be like display manger closed, pipwire and everything.

[Aqa-Ib]

True my bad, it is not After. You can use ExecStopPost probably in the systemd unit. You have to play with systemd to achieve this.

[littleblack111]

I see.. May I know wdym by hyprland.service though? like replace display manager and just start hyprland?

[Aqa-Ib]

Yes

[littleblack111]

Actually, that sounds like a good idea. since my display manager config is just autologin... ill have a try

I copied the sddm service file and modified:

[Unit]
Description=Hyprland
[email protected]
After=systemd-user-sessions.service [email protected] plymouth-quit.service systemd-logind.service [email protected]
PartOf=graphical.target
StartLimitIntervalSec=30
StartLimitBurst=2


[Service]
ExecStart=/usr/bin/Hyprland
; Restart=always
User=system
Group=system

[Install]
Alias=display-manager.service

[littleblack111]

nope. doesnt work. i'm pretty sure theres a service that sets xdg_runtime_dir. suggested by https://www.reddit.com/r/archlinux/comments/167v652/hyprland_refusing_to_start_says_xdg_runtime_dir/ its a pam_systemd probelm. which idk what the service is. thus this wont work...

[littleblack111]

please read the link provided. i am experiencing that issue. and if the env is not set. my runtime is prob not mounted as well... so hyprland will prob fail

[Aqa-Ib]

I am pretty sure that you can achieve it someway or another. I think that your service file is not good for hyprland. I havent use systemd to start hyprland before, but I would try login with my user in the tty and starting the service manually from it to see whats going on.

[littleblack111]

starting it manually would work

wdym by the user and group should be in my users service file? like ~/.config/systemd?

[Aqa-Ib]

User=youruser
Group=youruser

Also look at After= , because you just need your user to login first and after trigger it automatically. You can achieve it. Look https://wiki.archlinux.org/title/Getty#Virtual_console

[littleblack111]

wdym? I did:

[Service]
ExecStart=/usr/bin/Hyprland
; Restart=always
User=system
Group=system
ik i can do that. but i dont wanna login. i want it to be automaticlly on. dont worry about security cuz they would need to unlock the LUKS via password first in order to unlock the disk

[Vladimir-csp]

Ordering is reversed on deactivation. Setting After=unit1.service in unit2.service will delay deactivation of unit1.service until unit2.service is deactivated

Also, check this out.

[littleblack111]

cool repo!

[Vladimir-csp]

On the topic though, exec-shutdown might be handy anyway.
I.e. Labwc has both autostart and shutdown scripts.

[littleblack111]

yes. thats Y i'm filing this feature request. hope some maintainer sees this :D

[Aqa-Ib]

ik i can do that. but i dont wanna login. i want it to be automaticlly on. dont worry about security cuz they would need to unlock the LUKS via password first in order to unlock the disk

Look at the archwiki link I provided to you. Learn your init system to achieve what you want. You can ask on hyprland's discord too. Good luck.

[littleblack111]

i see you can auto login. but i think

On the topic though, exec-shutdown might be handy anyway.
as well

[Aqa-Ib]

You can set up the hyprland service after the autologin service running as your user. That should work fine.
