Since updating Kubuntu from 20.10 to 21.04 and my displaylink driver to 5.4 (necessary due to the 5.11 kernel in use on 21.04) my laptop hard freezes (meaning I have to press the power button to shut it down), when I power it up while my usb-c dock is plugged in.

I would like to report this behaviour to display link. Where can I find the related log files?

Please note that I do not want the log file of the latest successful boot, as this does not contain any info (the displaylink adapter is not plugged in). Hence, this is not a dublicate.

    All system log-files are normally in /var/log. The boot.log and syslog files are often a good place to start, but look around if others looks interesting. ,. – Soren A Apr 27 '21 at 11:30

    journalctl with the -b / --boot[=offset] might be worth a try - you can get a list of boot attempts and their offsets using journalctl --list-boots – steeldriver Apr 27 '21 at 12:12
  • @Bruni if you have a question about how to interpret the boot log, please ask it separately – steeldriver Apr 27 '21 at 12:55
  • @steeldriver fair point – Bruni Apr 27 '21 at 13:18

  • @waltinator The comment I had added would significantly alter the question and would therefore not be fair to be included in the same question. I had clearly indicated that when I said steeldiver that he made a fair point, so back off, – Bruni Apr 28 '21 at 05:54
