# Overlays: https://github.com/raspberrypi/firmware/blob/master/boot/overlays/README

#-------Display---------
# Max allocated framebuffers: Set to "0" in headless mode to reduce memory usage
# - Defaults to "2" on RPi4 and "1" on earlier RPi models
#max_framebuffers=0

# If you get no picture, set the following to "1" to apply most compatible HDMI settings.
#hdmi_safe=1

# Uncomment to adjust the HDMI signal strength if you have interferences, blanking, or no display.
# - Values from "0" to "11" are allowed, use values above "7" only if required, e.g. with very long HDMI cable.
# - Default on first RPi1 A/B is "2", else "5", on RPi4 this setting is ignored.
#config_hdmi_boost=5

# Uncomment if HDMI display is not detected and composite is being outputted.
#hdmi_force_hotplug=1

# Uncomment to disable HDMI even if plugged, e.g. to force composite output.
#hdmi_ignore_hotplug=1

# Uncomment to force a console size. By default it will be display's size minus overscan.

# Uncomment to enable SDTV/composite output on RPi4. This has no effect on previous RPi models.
#enable_tvout=1
# SDTV mode
#sdtv_mode=0

# Uncomment to force a specific HDMI mode (this will force VGA).
#hdmi_group=1
#hdmi_mode=1

# Uncomment to force an HDMI mode rather than DVI. This can make audio work in DMT (computer monitor) modes.
#hdmi_drive=2

# Set "hdmi_blanking=1" to allow the display going into standby after 10 minutes without input.
# With default value "0", the display shows a blank screen instead, but will not go into standby.
# NB: With "1" some applications (e.g. Kodi, OMXPlayer) cannot prevent display standby due to missing DPMS signal.
#hdmi_blanking=1

# Set to "1" if your display has a black border of unused pixels visible.
disable_overscan=1

# Uncomment the following to adjust overscan. Use positive numbers if console goes off screen, and negative if there is too much border.

##### Non-interactive Firstrun Setup #####
# On first login, run update, initial setup and software installs without any user input
# - Setting this to "1" is required for below settings to take effect
# - It is HIGHLY recommended to also set CONFIG_BOOT_WAIT_FOR_NETWORK=2, to force infinite wait for network connection during boot and prevent connection timeout errors.
# - Setting this to "1" indicates that you accept the DietPi GPLv2 license, available at /boot/dietpi-LICENSE.txt, superseding any setting of AUTO_SETUP_ACCEPT_LICENSE.
AUTO_SETUP_AUTOMATED=0

# Global Password to be applied for the system
# - Affects "root" and "dietpi" users login passwords and is used by dietpi-software as default for software installs which require a password.

# Software to automatically install
# - List of available software IDs: https://github.com/MichaIng/DietPi/wiki/DietPi-Software-list
# - Add as many entries as you wish, one each line.
# - DietPi will automatically install all pre-reqs (e.g. ALSA/X11 for desktops etc)
# - E.g. the following (without the leading "#") will install the LXDE desktop automatically on first boot:
#AUTO_SETUP_INSTALL_SOFTWARE_ID=134
