I deleted `"quiet splash"` from `GRUB_CMDLINE_LINUX_DEFAULT` in the GRUB config file.

And when I reboot with the command line, I can see the commands until it reaches `target reached restarting now`

And then.... nothing, it freezes there. So it is not possible to shut down.

It is a dual boot of Win10 with Ubuntu 16.04

I had a similar problem on launch but I fixed it on adding `acpi=off` after pushing the `E` key in the GRUB menu.

**EDIT**

I changed `acpi=off` to `acpi=noirq` and this gave me a freeze on restart and when I did force shutdown and restart it gave me a purple screen with nothing. I had to edit again from the GRUB menu to put it back to `acpi=off`

What else can I try?
