Ubuntu – How to hibernate from GNOME Shell

gnomegnome-shellhibernatepower-management

GNOME Shell doesn't have an option to hibernate in the session menu. I checked the GNOME Shell Cheat Sheet but hibernate is not mentioned there.

How can I hibernate my machine from within a GNOME Shell session?

Just install this GNOME Shell extension by sliding the slider. Your user menu should now show a few new extra options: Hibernate, and Power Off...

Open a terminal and run the following command:
```
gksu gedit /usr/share/polkit-1/actions/org.freedesktop.upower.policy
```
This opens up /usr/share/polkit-1/actions/org.freedesktop.upower.policy for editing.
In the org.freedesktop.upower.hibernate section, changed the the line <allow_active>yes</allow_active> to <allow_active>no</allow_active>:
Restart indicator-session-service so for the change to take effect:
```
killall indicator-session-service 
```

That's it, there should no longer be a Hibernate item in the session menu.

How to change the GNOME Shell theme?

Once installed, Click on Activities on top panel and search for "Advanced Settings" (or "Tweaks" or "Tweak Tool") and open it.
Under Shell Extensions enable User Themes extension (if it's not installed, you can install it from here) by clicking on ON/OFF switch.

Close 'GNOME Tweak Tool' and reopen it, Open themes settings, Click on browse button in front of Shell Theme and select your custom theme, Once updated click on drop down menu in front of browse button and select your theme. You'll see the changes take effect immediately. That's it!
