After I upgraded to Ubuntu Feisty Fawn 7.04 Linux distribution I noticed that one of my favorite laptop features suspend/hibernate worked quite baldly and slowly. It took up to few minutes to get laptop sleeping and then awake it. Both default suspend and hibernate features are cheesy in this Ubuntu version. The worst thing I faced was that after I got laptop sleeping and put it into my bag it was still working. This situation caused laptop overheating.

Thanks to heaven there is alternative suspend/hibernate utility for Ubuntu OS - uswsusp (I really don’t know who gave such a name for it). To get it working just install it with apt-get or aptitude (I recommend aptitude) :

sudo aptitude install uswsusp

When it’s done it would be great if you test it before making it default suspend/hibernate engine:

sudo s2disk

This will hibernate your system, to check suspend feature execute:

sudo s2ram
or
sudo s2ram -f

Working well? Great! Let’s make it default (including Gnome logout dialog). First of all download these files:

hal-system-power-suspend-linux
hal-system-power-hibernate-linux

Then backup Ubuntu’s original files to your Desktop by commands:

cp /usr/lib/hal/scripts/linux/ hal-system-power-suspend-linux ~/Desktop
cp /usr/lib/hal/scripts/linux/ hal-system-power-hibernate-linux ~/Desktop

Now it’s time to make uswsusp to be default in the system:

sudo cp hal-system-* /usr/lib/hal/scripts/linux/
sudo chmod 755 /usr/lib/hal/scripts/linux/*

Note: if you use Edgy just replace /usr/lib/hal/scripts/linux/ with /usr/share/hal/scripts.

Now you can use suspend/hibernate features normally without any obstacles
