My Ubuntu 12.04 is missing Hibernate option so after searching a little on Google I came to know that this can solve my problem
sudo nano /etc/polkit-1/localauthority/50-local.d/com.ubuntu.enable-hibernate.pkla
Fill it with this
[Re-enable hibernate by default]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes
Here is the link : How to enable hibernation in 12.04?
This simple tutorial is going to show you how to change the laptop lid close actions, including suspend, hibernate, do noting, and shutdown when the lid is closed in Ubuntu. In Ubuntu 12.10 & 12.04, hibernate is disabled by default, so this handy tutorial will also show you how to enable hibernate.
Here we go:
1.) To enable hibernate in Ubuntu 12.04 and Ubuntu 12.10.
Hibernate option is disabled by default in Ubuntu 12.04. Hibernate doesn't work in many cases with Ubuntu, so this decision was taken to avoid data loss/corruption that can happen when a user tries to hibernate his system.
So if you are quite used to hibernate feature, you will have to rely on a workaround by manually editing some system files.
a few days ago i was looking a way to make my laptop's hibernate process faster.
after searching on the internet, i found an intruction to install uswsusp for faster hibernate process.
'sudo apt-get install uswsusp'
'sudo apt-get install hibernate'
'sudo ln -sf /usr/sbin/hibernate /usr/sbin/pm-hibernate'
but, after i did that command line, now my laptop cannot hibernate.
I've add this following code to
/etc/polkit-1/localauthority/50-local.d/com.ubuntu.desktop.pkla
[Enable hibernate by default]
Identity=unix-user:*
Action=org.freedesktop.upower.hibernate
ResultActive=yes
When i choose to hibernate, the pc doesn't shutdown but i can see the text in the image in the link...
Help me please..I need to hibernate my computer..
Thanks
Since switching to Karmic, suspend and hibernate are not working consistently on my Toshiba Satellite. I have it set to hibernate when I close the lid, but doing so only turns off the screen. The suspend and hibernate keys on my keyboard also no longer work. When I select these options from the menu, the computer will suspend or hibernate properly.
I installed Ubuntu on my Windows 7 Sager laptop using Wubi. Hibernate (i.e. suspend to disc) is not an option from the power icon, only suspend, shutdown, etc. Hibernate is also not an option from my battery/lid close options. I understand that hibernation is disabled by default in Ubuntu 12.04. I tried running pm-hibernate but I get the following message:
Looking for splash system...
I'm trying to setup hibernate on my new rig, and I've gotten tuxonice working a few times, but then I had a failed hibernate, and sense then, I can't resume from a hibernate. TuxOnIce has the loading bar, and the text interface, and successfully brings the computer into hibernate. However when resuming from hibernate, the screen stays black, then displays random pixels everywhere, and hangs.
Whenever I go into hibernate or suspend it doesn't seem to work.
