Do we have similar measures? I see that GDM still depends on dbus-daemon.

But GDM still depends on dbus-daemon.

So what if gdm still requires dbus-daemon, the article you linked is about making dbus-broker the default systemd service.

I’m still a bit confused. Since dbus-broker has replaced dbus-daemon, why does GDM still depends on dbus-daemon? Is it a problem with GDM?

gdm depends on /usr/bin/dbus-run-session, which is provided by the dbus-daemon package Commit - rpms/gdm - bb7bcfdb36e64eaba91a6d5a8c47c4e1ef75d119 - src.fedoraproject.org

This is a technical limitation in GDM’s current design:

It doesn’t really seem like a big deal to me.

Thank you for your reply. It seems that this is indeed the current limitation of GDM.
