Dim screen when user is idle

You can make the computer screen dim after the computer has been idle (not used) for some period of time.

Dim screen on idle computer

  1. Maak het profiel user aan met de volgende regels:

    /etc/dconf/profile/user

    user-db:user
system-db:local

    local is de naam van een dconf-database.

  2. Create the directory /etc/dconf/db/local.d/ if it does not already exist.

  3. Create the key file /etc/dconf/db/local.d/00-power to provide information for the local database.

    /etc/dconf/db/local.d/00-power

    # Specify the dconf path
[org/gnome/settings-daemon/plugins/power]

# Enable screen dimming
idle-dim=true

# Set brightness after dimming
idle-brightness=30

  4. Create the key file /etc/dconf/db/local.d/00-session to provide information for the local database.

    /etc/dconf/db/local.d/00-session

    # Specify the dconf path
[org/gnome/desktop/session]

# The number of seconds of inactivity before the session is considered idle
idle-delay=uint32 300

    You must include the uint32 along with the integer key values as shown.

  5. To prevent the user from overriding these settings, create the file /etc/dconf/db/local.d/locks/power-saving with the following content:

    /etc/dconf/db/local.d/locks/power-saving

    # Lock screen dimming and idle timeout
/org/gnome/settings-daemon/plugins/power/idle-dim
/org/gnome/settings-daemon/plugins/power/idle-brightness
/org/gnome/desktop/session/idle-delay

    If you want to let the user change these settings, skip this step.

  6. Werk de systeemdatabases bij:

    # dconf update

  7. Gebruikers moeten zich af- en weer aanmelden om de systeembrede instellingen door te voeren.
