Most people need hibernation for their laptops.step is to install a tool called «uswsusp»
sudo apt-get install uswsusp
And by typing the below command you check if the suspend function works now….
sudo s2ram
Same goes for hibernation
sudo s2disk
Now once this is done, and all of the above commands work, they can be replaced with the old non-working commands that come with ubuntu.
But attention, before editing the system files, always make sure you back up the files in case something goes completely wrong.
sudo cp /usr/lib/hal/scripts/linux/hal-system-power-suspend-linux /usr/lib/hal/scripts/linux/hal-system-power-suspend-linux.bak
sudo cp /usr/lib/hal/scripts/linux/hal-system-power-hibernate-linux /usr/lib/hal/scripts/linux/hal-system-power-hibernate-linux.bak
This step is to replace the old commands with the new commands in
hal-system-power-suspend-linux
sudo nano /usr/lib/hal/scripts/linux/hal-system-power-suspend-linux
paste the following:
#!/bin/sh
/sbin/s2ram –force
hal-system-power-hibernate-linux
sudo nano /usr/lib/hal/scripts/linux/hal-system-power-hibernate-linux
paste the following again:
#!/bin/sh
/sbin/s2disk

(Please for hibernation problem
make share your swap is mounted correctly
so do this as root:)
sudo nano /etc/fstab
(you will need to enter root password)
(if the /etc/fstab is openned go to the line where you can read ” # swap was on /dev/…..”
immediatly after this line,I mean the next line ,be sure there is no ”#”.If there is on ”#” starting this following line ,just erease it.like this your swap space will be active for hibernation. after press ”ctrl+0” to save the changes. ”ctrl+x” to exit)
sudo apt-get install uswsusp
and restart your computer.
Ciao

I don not have # in the next line. And I still cannot find /usr/lib/hal/scripts/linux/hal-system-power-hibernate-linux and the same second either.
Also command s2disk has a same trouble as a previous.

Hi, could you be a little clearer with you instruction. When I try to save changes I get asked to save in either DOS FORMAT, MAC Format, PREFIX, BACKUP FILE or CANCEL.
So unable to save changes.
Remember a lot of people without much terminal experience need more help than those who are experienced, idiots guide please?
Thanks

I am running ubuntu 12.04 installed with wubi.
sudo apt-get install uswsusp
update-initramfs: Generating /boot/initrd.img-3.2.0-25-generic-pae
Warning: No support for locale: en_US.utf8
sudo s2ram
KMS graphics driver is in use, skipping quirks.
–> system goes into suspend, wake-up ok
sudo s2disk
screen goes blank, error message about a file not found (swap??), after a few seconds system returns to normal running
/etc/fstab
# UNCONFIGURED FSTAB FOR BASE SYSTEM
/host/ubuntu/disks/swap.disk none swap sw 0 0
#
# windows disk
UUID=…
Any ideas?

At sudo s2disk:
The message says “looking for splash system…none”.
Then,another message shows up shortly, and the system returns to normal.
syslog
“…Freezing of tasks failed after 20.00 seconds (3 tasks refusing to freeze, wq_busy=0):…”
NetworkManager, Sunbird-bin, Firefox are mentioned with trace backs.
The same thing sometimes happens at sudo s2ram, but that can be tried again, and then usually works.
How to do?
