Ubuntu – How to fix hibernate

hibernate

Suspend and Hibernate was not working in my Ubuntu 11.04 and I followed these instructions to fix the issue by installing uswsusp.

The commands s2ram and s2disk were working fine for me and hence I replaced the contents of hal-system-power-suspend-linux and hal-system-power-hibernate-linux as directed in the above link.

Now after my upgrade to Ubuntu 11.10, I am unable to hibernate my system. How to rectify this issue? Is there any config file which I need to change for hibernate to function properly?

Please make sure that your swap is mounted correctly. Edit the /etc/fstab/ file using the nano editor:

sudo nano /etc/fstab

When the /etc/fstab is opened, go to the line where you can read: ” # swap was on /dev/…..” immediately after this line, I mean the next line, be sure there is no ”#”. If there is a ”#” starting this following line, just delete it. Then press Ctrl+O and after that Enter to save the changes you made to fstab, then Ctrl+X to exit nano. Now your swap space will be active for hibernation after the next reboot.

sudo apt-get install uswsusp

...and restart your computer.

I too hate having to pass a URL so I will copy and paste the information and attach the web page to the bottom. I do not see this in your link.

While reading this, I noticed that hibernation may not work if you formatted with btrfs file system? So, how is hibernation permanently enabled in Ubuntu 16.04?

To make the Ubuntu hibernation process permanent, you need to create a new file using a text editor on the command line:

sudo nano /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla

The system requires root privileges to enable the hibernation option, hence, the command sudo should be added. You can use other text editors like vi, gedit, emacs, etc.

Now, copy and paste the following text to a file (use the mouse; keyboard shortcuts won’t work):

[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;org.freedesktop.login1.handle-hibernate-key;org.freedesktop.login1;org.freedesktop.login1.hibernate-multiple-sessions;org.freedesktop.login1.hibernate-ignore-inhibit
ResultActive=yes

Press CTRL+O to save, and CTRL+X to exit the nano editor.

Now, logout of your system and then login again. You will now see a hibernate option, along with the Shut Down and Suspend options.
