== Reboot/poweroff for unprivileged users == | |||
With the following rule, we can grant the permissions <code>reboot</code> and <code>poweroff</code> a machine to users in the <code> | |||
users</code> group. | |||
This is useful on a multi-user machine. It may also be of particular importance when using XRDP or other similar [[Remote Desktop]] solutions. | |||

Another option is <code>lxqt.lxqt-policykit</code>, which can be launched on login through the command <code>lxqt-policykit-agent</code> on e.g. Hyprland. | |||
== Start the authentication agent in dwm == | |||
If you use dwm patched with [https://dwm.suckless.org/patches/autostart/dwm-autostart-20210120-cb3f58a.diff dwm-autostart-20210120-cb3f58a.diff], you can add a command into <code>~/.dwm/autostart.sh</code> to start a polkit agent. Here take <code>mate.mate-polkit</code> for example: | |||
<syntaxhighlight lang=bash> | |||
#!/bin/sh | |||
# General stuff | |||
... | |||
/nix/store/$(ls -la /nix/store | grep 'mate-polkit' | grep '4096' | awk '{print $9}' | sed -n '$p')/libexec/polkit-mate-authentication-agent-1 & | |||
... | |||
</syntaxhighlight> | |||
Use this method, you won't need to change the codes even <code>mate.mate-polkit</code> gets an update. | |||
<syntaxhighlight lang=bash> | |||
#!/bin/sh | |||
... | |||
/nix/store/$(ls -la /nix/store | grep polkit-kde-agent | grep '^d' | awk '{print $9}')/libexec/polkit-kde-authentication-agent-1 & | |||
... | |||
</syntaxhighlight> | |||
The same but for <code>polkit-kde-agent</code> | |||
