FAQ

Hibernation does not work

Try launching from your terminal

systemctl hibernate

If it doesn't work, it means hibernation is disabled on your system. Please see:

https://askubuntu.com/questions/1034185/ubuntu-18-04-cant-resume-after-hibernate/1064114#1064114

or

Hibernation button does not show up, but systemctl hibernate works

If you are running Ubuntu, try putting

[Enable hibernate in upower]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes

[Enable hibernate in logind]
Identity=unix-user:*
Action=org.freedesktop.login1.hibernate;org.freedesktop.login1.handle-hibernate-key;org.freedesktop.login1;org.freedesktop.login1.hibernate-multiple-sessions;org.freedesktop.login1.hibernate-ignore-inhibit
ResultActive=yes

into /etc/polkit-1/localauthority/10-vendor.d/com.ubuntu.desktop.pkla

Otherwise check for similar settings for your distribution. Credit: https://github.com/arelange/gnome-shell-extension-hibernate-status/issues/41#issuecomment-565883599
