Make the screen dim after a specific amount of time when the user is idle.

# 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

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

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.

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.db/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.
