Ubuntu – Replacing default hibernate method to s2disk

11.10defaulthibernate

I have installed uswsusp module with 'sudo apt-get install uswsusp'. Now I am trying to replace the default hibernate method (as launched from the menu) with s2disk. I found information that I am to edit this file:

/usr/lib/hal/scripts/linux/hal-system-power-suspend-linux

Unfortunately the path '/usr/lib/hal' does not exist in my system. Also, the directory '/etc/pm/config.d/' exists, but is empty, and creating there a file '00_sleep-module' did not help. Please help.

Thanks !! A lot, that worked perfect. I was able to get s2disk to hibernate my Toshiba C640, but not restore it. By updating /etc/pm/config.d/00sleep_module and purging cryptsetup as per post on Ask Ubuntu , things started working well.

Although waking from hibernate Grub 2 looks like something is wrong as it is stuck on background for few seconds. Maybe its just grub or large 4 GB ram snapshot being loaded from disk. I will have to check.

Also, my LAN connection came back. I had serious doubts about it, since I had to custom compile Atheros Fast Ethernet card module into Kernel.

I am using kernel 3.2.0-27-generic with Ubuntu 12.04 LTs on Toshiba Satellite C640 Hardware. Steps I have followed 

sudo nano /etc/pm/config.d/00sleep_module

If you never touched this file OOTB it should be entirely commented. Please read it entirely. Add following line to end of file

SLEEP_MODULE="uswsusp"

Finally purge cryptsetup, I am not sure about this step, it may or may not help

sudo apt-get purge cryptsetup
