How do I change the length of time the lock screen appears for?

  • 772

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?

  1. Ubuntu 17.04 and earlier (Unity)

    Open System Settings, click Brightness & Lock and select a value for the screen turn off option, Turn screen off when inactive for:

    Choose your time delay in the drop-down menu.

    Ubuntu 17.10+ (Gnome Shell)

  2. 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.

    OR

    You can use x-screensaver as described here:

  3. Just had the same problem but could not resolve the issue with the answer provided by Kurshid Alam. On Gnome 3.28 using dconf-editor:

    The screen saver turns on automatically when the session is considered idle

    org . gnome . desktop . screensaver . idle-activation-enabled

    The easiest way to delay the screensaver is to increase the time limit for idle

    org . gnome . desktop . session . idle-delay

    Or using terminal

    gsettings set org.gnome.desktop.session idle-delay $((15*60)) && \
gsettings set org.gnome.desktop.screensaver lock-delay 0 && \
gsettings set org.gnome.desktop.screensaver lock-enabled true

    Beware of possible impacts on laptop battery charge due to other services affected by the idle status.

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