I just installed a fresh Ubuntu 12.04 (Precise Pangolin).

I noticed that, there is no screensaver settings, which is fine. I like to control the period of time after which the blank screen is shown,which automatically locks the screen.

I do not want to enable screensaver. I only wish to be able to change the idle time period required to lock the screen automatically. It seems to me, it is by default around 10-15 minutes.

Hi yes this is in the System Setting -> Brightness and Lock

Then you can change the amount of time to turn the screen off.

  • Also ... other Linux variations have this under screen saver settings.
