Debian Etch - Suspend/Hibernate (in KDE)

[Blender]

Hi everybody!

I am using Debian Etch (amd64) on my desktop PC. My question is: How do I get suspend/hibernate working properly? Also, how can I have these suspend buttons in the "Log Out" dialog of KDE?

Before Debian I was running SUSE and there I had a suspend to disk/ram option in KDE's "Log Out" dialog. I have also used Ubuntu (Dapper) for a couple of days and its GNOME "Log Out" dialog also had hibernate/suspend options.
Have the SUSE guys added this functionality themselves or is it normally present in KDE but somehow not detected/available on my machine?

I know that my hardware is capable of doing suspend. I just don't know how to configure it properly. I read somewhere about some scripts and configuration files... but didn't really understand how to configure it.

$ cat /sys/power/state
standby mem disk

If I try (as root) to write 'disk' or 'mem' to /sys/power/state, the computer suspends but cannot be restored afterwards. So I guess there's something about the hardware that needs to be configured.

Hope someone helps.

Thanks!

Suse and Ubuntu applied special patches to the kernel in order to make suspend/hibernate work better. Also, they use special scripts to suspend/hibernate the computer (other then just the simple echo -n "mem" > /sys/power/state).

If you are to use the suspend/hibernate fonctionnality, it is very well possible that it won't work correctly unless you use a patched suspend2 kernel, with a custom made suspend script, like this one :
