Is your desktop screen going dark or showing a blank screen when idled? By default, Ubuntu is developed with screensaver enabled. It is automatically activated when your computer becomes idled for roughly 5 minutes. When watching movies or online flash videos and the screensaver is activated, it darkens your display. If this is becoming a problem and you want to turn it off, then this brief tutorial is going to show you a single line command that will turn if off for you.
- Turn off screensaver in Ubuntu 12.04 (Precise Pangolin)
To get started, press Ctrl – Alt – T on your keyboard to open Terminal. When it opens, copy and paste the commands below, then press Enter to disable screensaver.
gsettings set org.gnome.desktop.screensaver idle-activation-enabled false
That’s it! Your display will never go dark or black again.
