Hi,
      I need support for systemd, can you direct this to some that can?

      I was running a Youtube Video (Redacted), and I realised that the Background Desktop was flashing (Black, then Normal), but not the Firefox Browser.

I then realised that Pulseaudio was not working (I believe?).

So, I did an update (sudo dnf update), no updates available.

Now, I have DBUS-Broker.service failing at Boot time ?

With

So, I >sudo balooctl disable, but with difference.

I have tried to update KDE directly, but nothing changes.

Now NetworkManager does not start, and the Desktop if freezing now and again?

I think iwd.service is not starting, so I'm starting Network manually.

Any ideas?

Roger Moore
