Ubuntu 18.04 stuck at shutdown

  • 772

I am having this weird problem in Ubuntu 18.04. My laptop gets stuck at the shutdown screen every time I use shutdown and I have to manually press the power button for 5 seconds to turn the machine off.

Before 18.04, I was using Ubuntu 16.04 and it never got stuck at shutdown.

Any fix for this?

shutdown xubuntu 18.04

  1. While none of the other answers here helped for me (encountering the same problem), I fixed it by switching from the X.org graphics driver to the propietary nvidia driver that is recommended under software&updates. Since then, reboot works flawlessly.

    My setup: Asus G Series Laptop G501VW, with Nvidia 960M graphics card.

    To do this:

    • open Software&Updates (top left: Click on activities and type "software". Pick software&updates)
    • go to "additional drivers"
    • select a nvidia driver instead of the X.org driver
    • reboot the system

  2. Same problem here on my laptop. After some observation, I found out that it has something to do with power saving mode specially automatic suspend.

    Go to Settings > Power then turn off all Automatic Suspend options. Also choose Blank screen to Never.

    Till Ubuntu team will figure out why suspend mode is interfering with shutdown process, this solved my problem.

    Hope this helps

  3. Try a couple of sudo reboots from terminal to see if it clears things up: 1st to try, reboot without writing wtmp file:

    sudo reboot -d

    If that reboots successfully then try your natural close down. If it doesn't reboot, try forced reboot:

    sudo reboot -f

    If this was an upgrade from 16.04 to 18.04, it may be worth considering a clean install.

  4. I had this problem and in my case it seems to be related to the Intel Bay trail CPU which is causing some firmware bugs.

    Anyway I have a solution which isn't the best but good enough for now

    Solution:

    • Open the terminal and run

      sudo -H gedit /etc/default/grub

    • Edit GRUB_CMDLINE_LINUX_DEFAULT="quite splash" so that it says

      GRUB_CMDLINE_LINUX_DEFAULT="intel_idle.max_cstate=1"

    • Save and exit, and write the changes to GRUB's actual config file:

      sudo update-grub
    • Restart your computer forcefully one last time

    Let me know if it worked or when you have a better solution

  5. There are scores of scripts that run when you shutdown. I'm still on 16.04 and for me these are the ones in /etc/rc0.d (which are really links to /etc/init.d). One of them may have a long delay set in what it does for stop.

    AFAIK these scripts are run in alphabetical order, so you can insert a few that would just log their execution somewhere, helping you spot where the delay is.

  6. Had the same problem on a brand new ASUS N705u. Found had to do with how the video driver installs which causes a conflict with the "secure boot" function of the BIOS. Solution: Turn the "secure boot" function off until other solution will become available.

  7. For my Lenovo E580 the solution was adding the open ubuntu graphics drivers from https://launchpad.net/~oibaf/+archive/ubuntu/graphics-drivers

    sudo add-apt-repository ppa:oibaf/graphics-drivers
sudo apt-get update

  8. Imad's suggestion: change 

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

    into 

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"

    This is the only solution that works consistently for me. Will take that back. Nothing on this page works for me. AMD Turion X64 Duo Core Toshiba A215

  9. I had the same issue after a kernel upgrade. Shutdown/restart command was working smoothly before the upgrade. But started freezing after the upgrade. I attempted all fixes that are mentioned here and various other forums but nothing seemed to work. So I started installing various versions kernels and checked up shutdown command with different kernels and found that my machine freezes for all kernels greater than the following version:

    linux-image-4.15.0-20-generic

    My PC has the following specifications:

    Intel Core i5-8250U
NVIDIA Geforce MX150 with 2 GB VRAM

    I had the same issue when I installed Kali along with Ubuntu. Searching for its solutions I found it was probably a GPU issue and disabling the generic nouveau driver might fix it.

    I applied the solution given below for kali:

    1. Check your apt sources as per https://docs.kali.org/general-use/kali-linux-sources-list-repositories
    2. Run apt-get update && apt-get dist-upgrade
    3. Create the following file: /etc/modprobe.d/nouveau-blacklist.conf
    4. Edit that file and add only one line that says blacklist nouveau
    5. Reboot your PC.
    6. Run apt-get install libcuda1 libnvidia-ml1 --no-install-recommends -y
    7. Dn not reboot your PC at this point. You must edit one file before doing so or your GDM greeter won't work
    8. Edit the file /etc/modprobe.d/nvidia.conf and comment out the second line that says remove nvidia-current rmmod nvidia nvidia-uvm, or delete that line. Make sure that file has only one line that says alias nvidia nvidia-current
    9. Run apt install nvidia-kernel-amd64 nvidia-kernel-common nvidia-kernel-dkms
    10. Reboot your PC.

    and it worked for my kali. Applied the same for my Ubuntu, and it worked.
