The only difference in journalctl between when the system boots with power and without is that when the system boots without power, I see two journalctl messages:
Sep 26 10:53:27 fenrir dbus-daemon[793]: [system] Activating via systemd: service name='org.freedesktop.UPower' unit='upower.service' requested by ':1.37' (uid=123 pid=1052 comm="/usr/bin/gnome-shell " label="unconfined") Sep 26 10:54:31 fenrir dbus-daemon[844]: [system] Activating via systemd: service name='org.freedesktop.UPower' unit='upower.service' requested by ':1.38' (uid=123 pid=1111 comm="/usr/bin/gnome-shell " label="unconfined") When the system boots with power, I see only one similar journalctl message: Sep 26 11:22:26 fenrir dbus-daemon[835]: [system] Activating via systemd: service name='org.freedesktop.UPower' unit='upower.service' requested by ':1.38' (uid=123 pid=1090 comm="/usr/bin/gnome-shell " label="unconfined") -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1845532 Title: power icon does not indicate charging if booted without power connected To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/upower/+bug/1845532/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
