How can I change power options to make my system "always on"?

Question

Power options in 12.04 system settings has only one option: "Suspend when inactive", while I can't see any obvious settings I can change so that the system is always on - without locking the screen after 10 minutes of inactivity.

How can I change power options to make my system "always on"?

Solution

You can change lock behavior from "Brightness and Lock" settings. Just click the lock slider to turn it off:

"Brightness and Lock"? Who would thought to look there for power option. I probably didn't expected to see the word "lock" besides brightness. Not that I see any brightness setting in that dialog :D

Maybe it does brightness on laptops? But the lock is still there :P Although I agree it should be placed somewhere more obvious or just labeled Lock Settings or something.
