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 🙂

Hi admin,
just wanted to say thank you for that awesome hint to uswsusp! That package got my suspend/hibernate back working after the default system stopped working on my laptop after an upgrade to Feisty.
Cheers!
