Public bug reported: When system boots up with TB16 dock connected, it detects all peripherals and displays properly. The login screen gets displayed on 3 displays. After providing a password and logging in, all 3 displays go blank for a short time (< 5 seconds) and then the desktop appears on all three. So far this looks to me like a totally correct behaviour.
However, after a few seconds after showing the desktop, even when I don't do anything, all screens suddenly flicker / go blank, and it looks like the docks undergoes a reset. After another few seconds the docks gets restarted and the desktop appears on all displays and everything works fine since then. This happens every single time I boot the system and login. This doesn't happen after resuming the system from sleep. By quickly opening /var/log/syslog before it happens, I managed to find out the moment of screens going blank correlates to fwupd start. I tried blacklisting thunderbolt and thunderbolt-power plugins, but this did not help. Is there any workaround? Could fwupd not reload the dock if it *doesn't update thunderbolt controller NVM*? In most cases the firmware update is not needed, so I can't see a reason for restart. A relevant systemlog fragment: p 23 16:23:03 p5520 systemd[3030]: Starting Zeitgeist full-text search indexer...
