After a recent update on my Linux system I get a dialogue window every few (5?) minutes with the same message:
Authentication is required to set one's own greeter properties.
It has a password prompt and "Details" that go
I have never requested a change to greeter settings nor do I intend to. I also do not enter my password in windows I did not open.
I have tried to find out which process opens this window but did not find anything specific. I suppose it is one of the useless mass processes started nowadays by the
systemd user session by default.
Perhaps I can stop AccountsService itself, would that help? Is it needed at all?
The desktop environment is XFCE4.
xwininfo and clicking into the window, and then calling
xwininfo -root -tree shows the following (excerpt from
xwininfo -root -tree output:
xwininfo: Window id: 0x6cb (the root window) (has no name) Root window id: 0x6cb (the root window) (has no name) Parent window id: 0x0 (none) (...) 0xa42341 (has no name): () 794x215+87+460 +87+460 16 children: (...) // no windows with names 0x18002dc "Authenticate": ("polkit-gnome-authentication-agent-1" "Polkit-gnome-authentication-agent-1") 786x187+4+24 +91+484
Which means this is due to
polkit-gnome-authentication-agent-1 (likely started by
/etc/xdg/autostart/polkit-gnome-authentication-agent-1.desktop) but we do not know which process initiates this, right?
