I am having hard time trying to hibernate kubuntu 12.04 It doesn't hibernate. instead it goes to the lock screen only.

I checked the swap and it's 10G and active. I tried to hibernate using the command "sudo pm-hibernate" and it worked. but, I want a better fix without using commands.

Thanks a lot in advance :)

If hibernatian works by using sudo pm-hibernate command when you want to hibernate.

You can enable the hibernate option in the menus. To do that, use your favorite text editor to create /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla. Add the following to the file and save:

[Re-enable hibernate by default]

The hibernate option is already enabled. but it just locks the screen without hibernation – Elshaer Jun 7 '12 at 18:24
What Kubuntu release are you running? – Mitch Jun 7 '12 at 18:29

"The document could not be saved, as it was not possible to write to /etc/polkit-1/localauthority/50-local.d/com.ubuntu.desktop.pkla. Check that you have write access to this file or that enough disk space is available." That's the message I get when I try this. Any help? I have 100 GB of space and I made sure I had permissions set to write. What am I supposed to do? – user70350 Jun 13 '12 at 12:45
This should either be a question or a comment in the other answer. However, did you use sudo when editing the file? – Dason Jun 13 '12 at 12:48
