Can't start timeshift

using artix, openrc, wayland, timeshift (mint maintained). Trying timeshift-gtk prompts me with 'admin access required', running it with sudo outputs:
Code: [Select]
Invalid MIT-MAGIC-COOKIE-1 key

(timeshift-gtk:28457): Gtk-WARNING **: 01:27:39.600: cannot open display: :0

Running timeshift-launcher as normal user:
Code: [Select]
localuser:root being added to access control list
==== AUTHENTICATING FOR in.teejeetech.pkexec.timeshift-gtk ====

==== AUTHENTICATION FAILED ====

(timeshift-gtk:28913): Gtk-WARNING **: 01:29:07.247: cannot open display: :0

What am i missing? Any logs  i can provide? Can't backup my system, will be grateful for any help.

The reason running the command with sudo won't work is because timeshift is being executed under a different user ( root in this case ) and does not have access to the Xorg server running under your normal user.

As for why timeshift-launcher gives this error under a normal user I do not know.

Wich polkit?

Anyway, if you dont use KDE/Gnome, or other big DE's like cinnamon or xfce, its mostly needed to start polkit by your self.

The link to the arch wiki helps you with that.

Or you go to https://github.com/hyprwm/Hyprland and ask them how to accomplish this.

I had only just 'polkit' installed, no particulara agent. So i installed polkit-kde-agent and added it to my compositor startup script /usr/lib/polkit-kde-authentication-agent-1 &. Now timeshift-gtk still doesn't work, but timeshift-launcher does. Thank you a lot. Marked as solved.

It depends what config files your choosen polkit agent delivers. Could be that KDE only delivers one for timeshift-launcher, wich maybe handles that. Dont know, im not using timeshift :-)
