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.
- I like the use of dconf profile files, but I believe we shouldn't tell users to echo config to new files. I think it would be better to tell users to create a new file in the proper location, then provide a code block which they can copy-paste into that file. --stefanwilkens (talk) 21:34, 14 October 2013 (UTC)
You can installAUR 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
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
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
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.
