Gnome desktop seems configurable in various ways: in "Gnome settings", with gnome-extensions, gnome-tweak-tool, gsettings or dconf-editor.



However, apart from this procedure to change the login screen background, which involves a little bit of glib compiling, I have found no way to customize the appearance of:



  • the login screen (font, position, color and size of the login boxes)

  • shield screen aka lock screen aka curtain (font, position, color, format and size of the clock, displayed messages, etc.)

I understand that Gnome philosophy is not to allocate much resource in tweaky-tweak-tweaking-tweakable stuffs. But I am suprised that such basic and harmless properties of these screens seem so difficult to access.



Is there a way I can access and tweak login / shield screen organization properties?

Are they hardcoded or is it just a matter of sneaking into a small curtain.xml or loginscreen.json?

Do I need to get into the sources and compile gnome myself?

          Not sure if this is a little too late but you can customize the values in /usr/share/gnome-shell/theme/gdm3.css and that does the trick. Just find the screen-shield-clock class and make your changes. One simple thing I did to make it a little nicer is set the font-weight to 300 and it improves the look a million times.

          • Hey, not bad. This could help a lot, cheers :) Have you found any piece of documentation regarding the meaning of these values? I couldn't find any. Also, do I need to restart or recompile something? I couldn't get any of my changes happening. The file I've found is called gnome-classic.css.
