You might have noticed that the suspend and hibernation function in ubuntu/kubuntu won’t work. While there’s no official fix, you might find this work around helpful, hope you enjoy!

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

2. 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

paste the following again:

#!/bin/sh
/sbin/s2disk

Good Luck, let me know if you come across any problems!
