Running dbus-monitor --system, shows a lot of these events:

signal time=1567100862.252579 sender=org.freedesktop.DBus -> destination=(null destination) serial=467227 path=/org/freedesktop/DBus; interface=org.freedesktop.DBus; member=NameOwnerChanged
  string ":1.381958"
  string ":1.381958"
  string ""

There's a new event coming in about every second.

I noticed that these events do not occur before calling startx.

I'm on Arch Linux 5.2.9 running i3.

Is this some sort of timer or heartbeat DBus uses?

The reason for these events was my i3 status line. It's defined in ~/.config/i3/config

status_command while ~/.config/i3/status.sh; do sleep 1; done

Inside status.sh, I call upower to get the current battery information of the laptop.

Removing the calls to upower caused the NameOwnerChanged events to cease.

In my case, my webcam had been troubled for a while. When I checked syslog, I could see the webcam being detected as keyboard and then being failed from being attached. I disconnected the webcam wire and it fixed the problem.
