I have the same problem - no restart or shutdown options from xfce4 and
can't do elevated operations, e.g. manage printers.

This machine is a recent installation converted to sysvinit after
installation. Although I also normally use runit as init, I haven't on
this desktop.

I thought this had initially been working but I may be mistaken: systemd
did not last long:

2024-11-11 22:47:43 install systemd:amd64 <none> 257~rc1-4
2024-11-11 23:04:40 install sysvinit-core:amd64 <none> 3.11-1
2024-11-11 23:07:01 install elogind:amd64 <none> 255.5-1debian3

I don't have any custom polkit rules. I do have additional settings
supporting login via samba AD. This issue occurs regardless of whether I
use that or shadow password to log in to X session. debsums -ac did
not suggest anything interesting.

Anything I can do or provide to help diagnose?
