power-management

I have the following problem with a fresh install of Xubuntu 12.04:

I set up power management options so as to send the machine to sleep after it's been idle for a while. My intention was to have it finish some lengthy numbercrunching and then fall asleep late at night when nobody's present to shut it down.

What actually happened, however, is that the machine goes to sleep whenever the desktop session has been idle for the specified amount of time, and it does not seem to care at all about CPU load, and I had to disable sleep altogether.

Is there any way to fix this?
