Comment 3 for bug 634624

Hello,

In Ubuntu, "pm-utils is responsible for getting the system into a state where it can be suspended or hibernated, and handling any cleanup after resume." So it definitely has to be installed on your system for suspend/hibernate to work. I have it installed on my machine, that first was a Maverick beta and then was upgraded to the final release.

So the problem sounds like a bad installation on your machine. Perhaps something went wrong during the installation/upgrade, or the media you used had defects.

I'll mark this issue as invalid, because It seems not possible for you to perform the installation again and get to the same state. So this problem is not going to be reproducible and the developers are not going to be able to get the information they required to fix it.

However, if you or someone else manage to install the system again and it doesn't have pm-utils, it will be really useful for us if you reopen the bug and add any information you might find useful.

Thanks again for reporting your problem.
