I recently set up a dual boot on my new laptop with an i7 8750h and a laptop grade gtx 1050, with Ubuntu 18.04 alongside Windows 10.

uname -r shows 4.18.7-041807

Any time I try shutting the machine down or rebooting it does not work. I tried a bunch of things like editing the grub config file and disabling secure boot and fast boot.

What else can I try?

The fix involved going to /etc/default/grub and changing the default line to GRUB_CMDLINE_LINUX_DEFAULT="noacpi" and then running sudo update-grub.

I also disabled fast boot and secure boot.
