How do I hibernate my computer?

Question

I tried the command

sudo s2disk 

but the OS said command not found so I went and installed

sudo apt-get install uswsusp

now the command worked, and the computer did hibernate, but it failed to resume.

I also installed

gnome-shell-extensions-alternative-status-menu

hoping that hibernate would show up in the menu, but it didn't. (I did press the Alt key)

Answer 1

in case you have any graphics card in your system make sure your currently installed driver has no hibernate/suspend issues.

I had similar issue of machine failing to resume, installing the latest graphics driver (catalyst 11.12 in my case) fixed it.

Answer 2

when you hold key ALT, and click power, you will see poweroff transe to hibernate, enjoy
