I recently installed Xubuntu 14.04 on a Dell Workstation.

Whenever I shutdown, two things happen. Either it shuts down and automatically restarts, or it hangs at shutdown with a black screen.

Searching for a solution I have tried the following:

  • used

    sudo shutdown -h now
sudo shutdown -P now
sudo init 0

  • amended and updated

    /etc/default/grub to GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"

  • checked the BIOS for Wake on LAN

    not an option for the DELL Precicion 7400 Workstation)

  • reinstalled Xubuntu

None of these have solved the problems so far.

Anyone have any other options for me to try?

    Did you read this older entry http://askubuntu.com/questions/26601/new-computer-hangs-on-shutdown-reboot-how-to-troubleshoot or this http://askubuntu.com/questions/349236/pc-restarts-after-a-few-seconds-when-performing-shutdown-or-suspend – TuKsn May 08 '14 at 13:36
  • Same problem here. Actually in my case was a result of some update I guess as it was working fine just few days ago. My laptop screen turns off after some minutes despite my settings. – lepe Sep 27 '14 at 13:41

    Have you tried updating the BIOS? – QwertyChouskie Jan 14 '16 at 22:40

I recall having similar issues many years ago that was strangely due to the video drivers. If you remove quiet splash from your /etc/default/grub and run sudo update-grub, you should be able to find the specific place where the shutdown is getting hung up.
