hyprpolkitagent fails when restarting hyprland

[GoldenEG]

The steps I did to reproduce this issue is by doing:

• Super + M (quits hyprland and goes to my session manager which is sddm)
• Launching back to hyprland with my session manager

I start hyprpolkitagent by doing this command in hyprland.conf:

exec-once = systemctl --user start hyprpolkitagent

This is the status of hyprpolkitagent when it fails:

I'm seeing this as well. My guess is that it's trying to start before polkit is ready... which is tricky since a systemd user-level service can't be depended on a system-level service

could you retest on the new build? the original symptom (result: core-dump after hyprland exit + relaunch) was on the qt agent. retested locally on the current build (#50 + #52 + #54 + #56 + #57): systemctl --user restart hyprpolkitagent followed by coredumpctl list --since '5 minutes ago' hyprpolkitagent returns No coredumps found. session resolution also has a three-step fallback now (XDG_SESSION_ID -> GetSessionByPID -> logind User.Display) which was the related #53. if it still cores on relaunch on your setup please attach coredumpctl info <pid>
