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. --[[User:Stefanwilkens|stefanwilkens]] ([[User talk:Stefanwilkens|talk]]) 21:34, 14 October 2013 (UTC)

:: I originally copied the content from the login screen section in the GNOME article over here because there was a merge request. I feel the quality of this content you have posted here is far higher so I have replaced what was there with this. This covers exactly the same points as the original content and a few more as well so no info is lost. In the original content it said the gsettings tweaks wouldn't work without "exporting the gdm session variables" but the section explaining how to do that no longer existed so they wouldn't be much help anyway.

You can install {{aur|gdm3setup}} 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|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 {{ic|/etc/systemd/logind.conf}}:
+
 
+
HandleLidSwitch=ignore
+
 
+
==== 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 [[Beginners'_Guide#Non-US_keyboard|Beginner's Guide.]]

"Make the power button interactive" no longer possible with GDM 3.18

I have been attempting to change my power button's behaviour from suspend to interactive as per the instructions here without success. Looking into it, it seems with Gnome 3.18 the developers removed the "button-*" configuration options: https://bugzilla.gnome.org/show_bug.cgi?id=753713 Rjackson (talk) 17:47, 1 November 2015 (UTC)

It would seem the options to change the power button, found in org.gnome.settings-daemon.plugins.power as the power-button-action, currently allows 3 different values: nothing, suspend, and hibernate. Why anything else isn't available is beyond me. I've set it to nothing at the moment, just to avoid accidentally suspending when I mean to power down. While the bug report referenced by Rjackson describes the issue, the resolution makes this confusing, as it indicates a fix was pushed out previously. Perhaps the fix resulted in the current behaviour. CubeTheThird (talk) 06:46, 21 November 2015 (UTC)
Thanks for looking into this both of you. If the OP could that the suspend/hibernate/nothing options do still work then the section can be updated accordingly. -- Chazza (talk) 15:55, 21 November 2015 (UTC)
