I am being troubled by the infamous shutdown hang/freeze error. Whenever I shutdown mint, only the first dot on the splash screen turns green and then it kind of freezes. I also had this prob on Ubuntu 16.04.I intend to use linux for gaming. Here are my system specs-

Turning off the network before shutting down makes no difference, so it isn't due to unreachable remote servers.

Reboot works fine.

Result of journalctl --boot -1 -e --full

Specifying boot ID has no effect, no persistent journal was found

Verbose booting had a fail line, which said something about not being able to load kernel modules.

Result of verbose shutdown(last two lines):

[OK] Reached target shutdown.
[54.278173] reboot: power down

Result of systemctl status

  • Run journalctl --boot -1 -e --full, edit your question, and put the relevant output there. This will show people what systemd thought that it was doing at the time.

  • The journal is what tells people what was going on. "It kind of freezes." does not. Unfortunately, you've configured your system to discard the journal at every shutdown, rather than store it persistently in /var/log/journal, so you cannot tell the world what the journal recorded, and people cannot then diagnose from that what was (or was most likely) going wrong.

I fought two days with Linux Mint 18.3 system on a Dell 5577 laptop (Nvidia 1050). On shutdown or reboot the screen was black and nothing happened.

None of the following helped :(

  • modification of grub (adding GRUB_CMDLINE_LINUX="apm=power_off", "acpi=force", etc.)
  • disabling EuP (powering USB port on the switched off computer)

What helped :)

  • Select Menu -> Administration -> Driver management -> select nvidia driver instead of nouveau, wait patiently, because it lasts a little, first reboot or shutdown will fail, but after restart it finally works fine! :)

    Exactly the same for me with Dell XPS 15. Unfortunately the Nvidia drivers are unusable as just watching a fullscreen video is enough for them to drive the fans so hard you can't actually hear anything. This occurs with Prime set to Nvidia or Intel graphics.

  • If you get access only to the terminal or you just prefer the terminal, take advice from How to change the graphics card driver via terminal?. Commented Dec 26, 2020 at 12:00

What worked for me in Gentoo linux (kernel 4.17.5) solving this problem was to add as an option for the nouveau driver de following:


(nouveau.vram_pushbuf=1 when nouveau is inserted in the kernel).

I discovered this from an error message at the end of the halt process. The system hanged when trying to shut off the video as the final porcess for a complete shutdown without this option for my nvidia GPU.


This problem was actual for me too. What is the most interesting - when I closed first manually user session and then shut the system down, everything went smoothly without any delay. Today I devoted some time to solve the issue and here are some results. The problem arises because the system waits at the shutdown for some thing which in its opinion must happen. The very thing is individual for each separate case. In my case it was even two problems one of which I've found. The system was looking for a hard drive which didn't exist. How so? Because I've experimented with some other versions of Linux and chose for all versions the same drive device as swap. During installation of the second Linux, UUID of the device was changed but in system files of the first Linux it remained unchanged. But, once again, - it was my problem, yours may be not alike at all. After I fixed the above problem, I still had another one. I lost my hope and just gave up to the temptation to solve the problem with a brute force. I changed in the /etc/systemd/user.conf and /etc/systemd/system.conf files parameter DefaultTimeoutStopSec from 90 seconds to 5 seconds. Don't forget to uncomment the line (to remove # sign in the beginning of the line with the parameter DefaultTimeoutStopSec).

Now it works fine, system shuts down very fast.

  • As I did not only have the hanging Linux Mint 19.2 at shutdown time when it appeared at first, but after a few times of forced closed Linuxes even at start-up time, this answer helped me the most to find the solution in my case. I had plugged in an external drive during installation of Linux, and I accidentally installed the bootloader on my external drive. The solution for this was to add a new grub (Ubuntu's bootloader) to my main Linux disk instead. I have added a separate answer. Commented Dec 26, 2020 at 13:53

Another possible solution - especially for newer hardware using (U)EFI - is to add the boot parameter apm=power_off. You can add it to the definition of GRUB_CMDLINE_LINUX_DEFAULT in /etc/default/grub or add the line if it does not exist yet.


Then update the grub installation according to your operating systems manual, e.g:

update-grub # Debian/Ubuntu
grub2-mkconfig -o /boot/efi/EFI/fedora/grub.cfg # EFI on Fedora etc
grub2-mkconfig -o /boot/grub2/grub.cfg # BIOS

i assume your system powers off after the 54s? its possibly a hung process, if you have a lot of disk activity on shutdown check /var/lib/systemd/coredump/ for files, you could then turn off core dumps (as a work around rather than root solution)


Turning Off USB 3.0 legacy mode or usb3.0 configuration in pre-os in BIOS, worked for me.


Linux Mint 18.1:

My problem was that my new PC hanged at unsystematic moments at shutdown/power off. I had to push the on/off button for several seconds (also mechanical power off).

After I changed a setting in the UEFI/BIOS the problem was gone:

  1. Open the UEFI/BIOS:

  2. Advanced → Powermanagement → EuP-setting disabled

  3. Exit by saving the settings

Then restart your computer and everything should be OK.

    What's the EuP setting do, or stand for?

For me this problem was fixed after I deleted the "quiet" and "splash" values from the GRUB_CMDLINE_LINUX_DEFAULT parameter in grub.


Linux hanged at shutdown and needed to be force-closed with the power button, then it even hanged at start-up as well, going into an emergency menu. The reason: I had installed the Bootloader on the external drive. As soon as that external drive was not plugged-in, both shut-down and start-up were hanging. When it was plugged in, everything worked well.

Credits for the following solution go to @DongJuang's answer which gave me the idea of searching for "linux does not start without external drive plugged in", giving me the actual solution at Can't boot without Flash Drive plugged in --> search for @SirCharlo's answer, starting with:


The problem

Grub, Ubuntu's bootloader, was installed on the flash drive, and not on your internal hard drive, as it should have been.

For the full solution, see the link.

p.s.: Before, I had tried to upgrade the NVIDIA driver and improve its configuration so that Nouveau driver was not assigned anymore, but did not solve it in this case.
