Title:
  Firmware update daemon resets displays connected to Dell TB16 dock
  soon after every first login

Status in fwupd package in Ubuntu:
  Fix Released

Bug description:
  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:
