I bought a new laptop (Dell Inspiron 7577) and I installed Ubuntu 16.04 LTS on it. Before I did update and upgrade I tried to shutdown and reboot and it all worked properly, but after the
sudo apt-get update && sudo apt-get upgrade it didn't work anymore.
What happens when I try to shutdown is: My screen just instantly freezes and I can't do anything more. Then I have to shutdown by holding the power button.
I've tried several things like:
- all different shutdown or reboot commands in the terminal (like:
shutdown -h now,
- reinstalling ubuntu 18.04 LTS
- changed in
/etc/default/grub the line
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash" to
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force".
Then I tried doing a shutdown in the terminal before I logged in(Ctrl+Alt+F2). Luckily there came a output put it was also hanging. Here's the ouput:

Now I recently downloaded Ubuntu 18.04 and I have the exact same problem.
Could anyone help me to solve this problem?
