Hibernate vs Suspend

Sticky

Hi-

Novice user here...looking for help with an old laptop. The laptop can't wake up from suspend in all operating systems including Windows. It does however, wake up from hibernate mode in Solus. I set the power options to hibernate when I press the power button, but I cannot change the auto suspend/sleep to hibernate.

Is it possible to change the default suspend when not in use to hibernate?

Thx!

Sebastian

This question cannot be properly answered without knowing what DE you are using.

Gnome 48 all updates installed.

Can you run these 2 commands in terminal and check if they do what you want?

gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-battery-type 'hibernate'

gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type 'hibernate'

edit: and by check I mean wait and see if it now hibernates instead of suspends. Cause you won't see any real change in GNOME settings itself

Ok, just entered those commands and waited. The normal gnome notification appeared with "hibernation" instead of "suspend". Let the computer enter hibernation....and yup, works perfectly.

Thank you very much 🙂

Glad to hear. There is more to consider, though.
These are per user settings. So, if you have more than one user account set up on your system, you need to run these 2 commands for each user.
Then there is the issue of GDM. After booting, the system runs the display manager (where you enter your user credentials to log in). For GNOME, the display manager is called GDM.
GDM has it's settings of it's own. The default setting is to suspend computer if you haven't logged in within 5 minutes after boot.
These settings can only be changed as "gdm" user.

To do so, open an terminal and run:
sudo su - gdm -s /bin/sh
to become gdm user. Then run
gsettings get org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type
and
gsettings get org.gnome.settings-daemon.plugins.power sleep-inactive-battery-type
to see what is set. I expect both commands to output 'suspend'
To get a list of valid values, you can run
gsettings range org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type
You can now either chose to set GDM inactivity behaviour either to 'nothing' or 'hibernate'
to do so, run
dbus-launch --exit-with-session gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type 'nothing'
(or hibernate) and
dbus-launch --exit-with-session gsettings set org.gnome.settings-daemon.plugins.power sleep-inactive-battery-type 'nothing'
(or hibernate)
To check if settings have been altered succesfully, you can again run
gsettings get org.gnome.settings-daemon.plugins.power sleep-inactive-ac-type
and
gsettings get org.gnome.settings-daemon.plugins.power sleep-inactive-battery-type
and check output.
then enter exit to quit acting as gdm user.

The power/logout menu in quick settings in right corner in top bar will still list "suspend" option.
You can adjust this by installing and configuring(with extensions app) this extension:
https://extensions.gnome.org/extension/755/hibernate-status-button/

edit: ignore the comment on the extension page where a user suggest to modify /etc/polkit-1/rules.d/10-enable-hibernate.rules. This doesn't seem to be necessary according to arch linux forum

And then there is actually one more thing to consider: lid behaviour.
Default setting is: Closing laptop lid triggers suspend.
GNOME does not offer option to set lid behavior to nothing. Though there is a python script that can be run to inhibit lid behaviour in user session. (each time you log in, so in autostart)

You kind of have to check if closing lid will now also trigger hibernate instead of suspend after you have run the commans I gave you in earlier post. Because that I don't know.

edit: this link https://forum.manjaro.org/t/automatic-hibernate-and-on-lid-close-on-manjaro-gnome/107089/2 suggest that a different file has to be edited for lid closing behaviour

Interesting. I didn't know that about GDM. Thanks for all the tips!

Sebastian

You are welcome.
