how to disable hibernate option?


I am using Suse 11.0. I would like to set up the desktop as a home server. I would like to know how I could turn off automatic hibernation.

The last time I had kept it running for some time, I could not get it up (in spite of playing with my mouse and keyboard for a while) and had to forcefully reboot the machine:’(

The Suse topic on:
Pm-utils - openSUSE
talks about a file “/usr/lib/pm-utils/default”
However, I don’t understand which option to use to disable hibernation.

Thanks in advance
