When my screen is locked and I then reawaken it, by moving the mouse or pressing the keyboard, the password entry screen appears. How can I change the amount of time that is taken before the password entry screen turns off?

To be specific:

  • I lock my screen Ctrl+Alt+T
  • Screen goes blank
  • Move mouse to bring up login screen
  • If I do nothing else the screen turns off again after 1 minute

In my Brightness and Lock settings I have the screen set to turn off and lock after 10 minutes, but I can't see a setting to determine how long it takes for the screen to turn off after the lock screen has been woken. It seems to be set to 1 minute by default, can this be increased/reduced?

May I know why do you want to change that option? – Khurshid Alam Jul 7 '13 at 13:36
I am about to go back to 13. I can't find a way to keep the machine from locking itself about every ten minutes. I am so over it. – user293278 Jun 13 '14 at 16:26
Not sure but this might be some of your help [ How to adjust screen lock settings on Linux desktop ]( You might need to install dconf-editor – Prabhat Kumar Singh Jan 9 '15 at 10:58
@KhurshidAlam, May I answer for the asker? For example, when you work in two environments in one computer - Windows as a host machine and Ubuntu in VM. So sometimes Ubuntu locks your session when it is not desirable. – Green Aug 13 '15 at 3:46

You can not do that anymore in Gnome3.

In gnome2 you can change lock-screen timeout from gnome-screensaver settings.But In Gnome 3.2, gnome-screensaver doesn't exist, and screen locking is part of Gnome Shell.

They have reimplement some function, but not all. On Ubuntu you can access all power-related settings with dconf-editor from org.gnome.settings-daemon.plugins.power.


You can use x-screensaver as described here:

How can I change or install screensavers?

this doesn't affect the length of time that the password entry screen appears for – coversnail May 28 '12 at 15:42

Press the windows button to get the unity search, then type lock in the search bar. Open brightness and lock and change the timeout.
