Hi all,

After upgrading from 11.10 to 12.04 (yes, I know I'm a bit late), hibernation has stopped working from the KDE button.

Whenever I go into hibernate or suspend it doesn't seem to work.

Ubuntu 12.04 64bit refuses to hibernate when battery is critically low. Instead it does a complete shutdown which is unnecessary and can cause loss of data.

I have enabled Hibernate (pm-hibernate) on following the common instructions I tested pm-hibernate it is works fine when run manually.

I have set my power options to hibernate "When Power is Critically Low".

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.

This simple tutorial will show you how to easily get back hibernate option in system menu with 3 commands in Ubuntu 12.04. Hibernate has been disabled in Ubuntu 12.04 by default.
