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: poweroff, reboot, shutdown -h now, halt)

- 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?

How about trying old linux-kernels ? --- for example, v4.0-vivid, v4.1-wily ~ v4.5-wily

1. 
   

   Install ukuu:

   
   
   

   sudo add-apt-repository ppa:teejee2008/ppa
   sudo apt-get update
   sudo apt-get install ukuu
   

   
   


2. 
   

   Check the list of available kernels:

   
   
   

   sudo ukuu --list
   

   
   


3. 
   

   install old kernels:

   
   
   

   sudo ukuu --install v4.5-wily
   

   
   


4. 
   

   Remove current kernel:

   
   
   

   • reboot by advanced mode and choose old kernel.

   
   
   • 
     

     open terminal.

     
     
     

     sudo ukuu --remove (current kernel)
