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"?

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 – zetah Jun 4 '12 at 10:56
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. – izx Jun 4 '12 at 10:59
For those looking for the Brightness and Lock feature in Ubuntu 12.04 with Gnome Classic: Applications > System Tools > System Settings – Sander Dec 8 '12 at 16:15
