So after some fiddling i got hibernation to work on 19.04 (short pause and clap on the back). Actually it was not that terribly difficult which makes me wonder why this quite essential functionality is not enabled by default, but that is another topic.
sudo hibernate works from the command line, meaning the system wakes up/resumes correctly.
So now i want/need a UI for this. But when i “Hibernate” in the user indicator, it does not hibernate and then boots fresh when started. I have tried to find out what it actually does when that option is pressed (including reading budgie-desktop code), but could not.
And there is no “Hibernate” option in the what do do if power button is pressed drop down.
I have reached the end of my limited skills and would appreciate help.
