12.04 Screensaver – How to Disable Blank Screen


After my computer with ubuntu 12.04 has been idle for a short while, the screen will go blank, and even enter standby mode. I have tried this:

  1. System Settings -> Brightness and Lock -> Turn off screen… set to "Never"
  2. System Settings -> Power -> Suspend when… set to "Don't suspend"

This doesn't change anything.

How can I make sure that the screen will always remain on, forever?

Try opening a terminal with Ctrl+Alt+T and then enter the following:

gconftool-2 --type bool --set /apps/gnome-screensaver/idle_activation_enabled "false"
