I would propose the follwing "configuration section. Most of the subsections are easier and up-to-date versions of those on the Gnome page and on the GDM page. No need to export variables anymore. If this is ok we should also merge the Gnome page.


You can install gdm3setupAUR from the AUR to configure GDM, or use the following instructions that use dconf profile files.

Login background image

To change the wallpaper of the login screen use

# mkdir /opt/login
# echo -e "[org/gnome/desktop/background]\npicture-uri='file:///opt/login/wallpaper.jpg'" > /etc/dconf/db/gdm.d/01-background
# cp [YOUR FILE] /opt/login/wallpaper.jpg
# dconf update

where [YOUR FILE] needs to be a *.jpg picture.

Logo on login screen

To display a logo on your login screen use

# mkdir /opt/login
# echo -e "[org/gnome/login-screen]\nlogo='/opt/login/logo.png'" > /etc/dconf/db/gdm.d/02-logo
# cp [YOUR FILE] /opt/login/logo.png
# dconf update

where [YOUR FILE] needs to be a *.png picture.

Larger font for login

To change the font size of the login screen use

# echo -e "[org/gnome/desktop/interface]\ntext-scaling-factor='1.25'" > /etc/dconf/db/gdm.d/03-scaling
# dconf update

Turning off the sound

This tweak disables the audible feedback heard when the system volume is adjusted (via keyboard) on the login screen.

# echo -e "[org/gnome/desktop/sound]\nevent-sounds='false'" > /etc/dconf/db/gdm.d/04-sound
# dconf update

Make the power button interactive

The default installation sets the power button to suspend the system. Power off or Show dialog is a better choice.

# echo -e "[org/gnome/settings-daemon/plugins/power button]\npower='interactive'\nhibernate='interactive'" > /etc/dconf/db/gdm.d/05-power
# dconf update
Warning: Please note that the acpid daemon also handle the "power button" an "hibernate button" event. Running both systems at the same time may lead to unexpected behaviour.

Prevent suspend when closing the lid

On some systems it happens that your laptop suspends when you are closing the lid despite having set the options Laptop lid close action on battery and Laptop lid close action on AC to blank. If this is the case, append the following line to /etc/systemd/logind.conf:


GDM keyboard layout

GDM does not know about your GNOME 3 desktop keyboard settings. To change keyboard settings used by GDM, set your layout using Xorg configuration. Refer to this section of the Beginner's Guide.
