Maybe it serves to describe my current situation first:
- installed ubuntu on virtualbox (btrfs)
- created btrfs partition on my laptop
- booted on a live distro, used btrfs send/receive to transfer the root subvolume from the virtualbox
- set up grub so I can now boot my laptop from the ubuntu subvolume
The problem that arises: I can boot ubuntu, but I cannot reboot or shutdown the system. Whenever I click shutdown, or issue a 'shutdown now' command, the system freezes completely. I have a feeling that this is because ACPI is not installed, but I'm in doubt why this could be. Does the ubuntu installation detect that virtualbox does not need ACPI, so it does not add it? I have verified that no acpi service is running in the distro.
I have done this for an ubuntu 16.04 and an arch installation, both with the same conclusion / problem. My question is: is this really because of ACPI? Am I missing some other functionality due to this transfer of virtual to physical? Is the problem solved by simply installing ACPI packages in ubuntu / arch?
