Ubuntu: Can't boot my MacBook Air 2017 after sudo pm-hibernate



Question:

Looks like hardware simply does not support such a command. Whenever I try start Ubuntu (> 16), it tries to boot and in 2 secs screen became totally black. Nothing helps.

Just don't tell me I need to reinstall it.


Solution:1

As Steve said in the comment, there has been a problem with hibernation in some of the kernels shipped with ubuntu, which is described here: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1743094

From my limited reading, it seems to have started at 4.13.0-25, and still be a problem in 4.13.0-32

After I encountered this, I could still get into GRUB. I used Advanced options for Ubuntu > Ubuntu, with Linux 4.8.0-53 (recovery mode), and ran swapoff --all in a root-shell, ran fsck, and updated grub. After doing this, I was able to boot into my system again :) -- all steps might not have been necessary though.


Solution:2

In case you don't have an old kernel that you can use to boot the system, install an older kernel using live cd as described in How to restore a system after accidentally removing all kernels?
