Thank you so much! This solution really works for me on Zorin 16, hibernation is now an option I can choose in Settings - Power:
As a Windows user I'm accustomed to run any command with a bat-file, on my Windows 10 laptop I have different bat-files for Hibernate, Sleep, Shutdown and restart, so I can quickly do any of that. Would be nice if there was a way to create shortcuts to something similar on Zorin.
