My operating system is Ubuntu 17.10. When I shut down my laptop, it takes about half an hour or more to turn off. What's the problem? With Ubuntu 17.04 this was not the case.

    What do your logs say? – user535733 Oct 25 '17 at 19:31
  • Try `sudo poweroff` and see if it goes down in a timely manner... – George Udosen Oct 25 '17 at 19:34

  • You could switch to a terminal with `CTRL+ATL+F1`, login and then type `shutdown -h now`. The messages there should give you more hints. Feel free to post them in the post, so we can investigate further. – noreabu Oct 25 '17 at 20:40
  • What method do you use to turn off the laptop? What laptop is it (manufacturer and full model number)? – pbhj Oct 25 '17 at 21:18
  • I think this is version specific. Maybe related to [Kworker blocked for more than 120 seconds](https://askubuntu.com/questions/965856/kworker-blocked-for-more-than-120-seconds-ubuntu-17-10) – Zanna Oct 26 '17 at 15:10

  • Try ctrl-alt-f1 to switch to a console, run `top` and see if there's anything at the top of the list that looks unfamiliar, note that down, don't close top yet. Ctrl-alt-f7 will switch you back to your GUI session, do your usual routine for shutdown, do ctrl-alt-f1 again, see what is in the list that wasn't there before or that is higher up than before. You could also try `sudo shutdown -h now` from the console, or `sudo poweroff`. Is that faster, do any errors get reported? Whilst shutting down you can `tail -f /var/log/syslog`which may give some clues. – pbhj Oct 27 '17 at 11:38
