Good family, I am looking for the option to deactivate what is the battery saving perhaps, that directly the screen stays on and does not ask me for username and password when I leave it inactive. I work with 3 computers on the desk and I can't keep moving the mouse all the time while doing something else.
Maybe something here will help you. If all else fails, you can install "caffeine" as a work-around to fool the system that the mouse is moving. Remove blank screen after inactivity - #4 by zabadabadoo
