Ubuntu Hibernation Tricks

Test if hibernate works 

Before getting started, press Ctrl+ALt+T on your keyboard to open the terminal. When it opens, run:

sudo pm-hibernate

Enable Hibernate in System Tray Menu:

The indicator-session was updated to use logind instead of upower. Hibernate is disabled by default in both upower and logind.

To re-enable hibernate, run the commands below one by one to edit the config file:
sudo -i

cd /var/lib/polkit-1/localauthority/50-local.d/

gedit com.ubuntu.enable-hibernate.pkla

Tips: if the config file does not work for you, try another one by changing /var/lib to /etc in the code.

Copy and paste below lines into the file and save it.


[Re-enable hibernate by default in upower]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes

[Re-enable hibernate by default in logind]
Identity=unix-user:*
Action=org.freedesktop.login1.hibernate
ResultActive=yes




Restart your computer and done.
