I just installed Ubuntu 17.10 on my Asus n56vz laptop, and got a couple issues. The first one with display settings (I asked about it in another post). The second one with ACPI. There are many ACPI errors in log files, laptop doesn't reboot or shutdown, the laptop doesn't suspend when its lid is closed, etc.

Update: I was able to fix the reboot issue by editing the grub file:

sudo gedit /etc/default/grub
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash acpi=force"
sudo update-grub

Update: The above solution worked well for a few reboots only.

Update: Please find below a list of ACPI log messages

  • "there are many ACPI errors in log files" so we are going to need to guess what these are? Please add them to the question otherwise we have absolutely nothing to go on – Rinzwind Jan 16 '18 at 9:28

Most of these ACPI issues were resolved by switching from Nouveau display driver to the Nvidia 384.111 driver. Now I can reboot and shutdown my laptop without any problems, though I still have a few ACPI errors.
