I am aware from other posts that you can change e.g. the login screen background by modifying the css selector #lockDialogGroup in gdm3.css that you get when extracting the .gresource binary.

What is the equivalent for changing the clock / time font in the lock screen (screen shield)? I tried changing .unlock-dialog-clock and .unlock-dialog-clock-time but to not much result. Am I targetting the right selectors?

EDIT after discussion:

My workflow is as follows:

extract / edit / compile in ~/.local/share/gnome-shell/theme/Pop-modified, which is under version control (see below):

dedicated folder for editing files; trac

To apply the changes, I run the following command:

sudo cp ~/.local/share/gnome-shell/theme/Pop-modified/gnome-shell-theme.gresource /usr/share/gnome-shell/theme/Pop-modified/gnome-shell-theme.gresource

which is where gdm3-theme.gresource is pointing to, using update-alternatives (see below):

➜ update-alternatives --config gdm3-theme.gresource
There are 3 choices for the alternative gdm3-theme.gresource (providing /usr/share/gnome-shell/gdm3-theme.gresource).

Selection    Path                                                                   Priority   Status


0            /usr/share/gnome-shell/theme/Pop/gnome-shell-theme.gresource            20        auto mode
  1            /usr/share/gnome-shell/gnome-shell-theme.gresource                      10        manual mode

The actual edits are done as follows:

  • Rename gdm3.css and gnome-shell.css to gdm3-original.css and gnome-shell-original.css respectively.

  • Create new files called gdm3.css and gnome-shell.css, import the original css files and make all desired changes to these files.

Currently, the edits I made under #lockDialogGroup is in effect but not those under .unlock-dialog-clock.

GNOME shell version:

➜ gnome-shell --version
GNOME Shell 3.36.3

Contents of /usr/share/gnome-shell/modes:

➜ ls /usr/share/gnome-shell/modes
initial-setup.json  pop.json  ubuntu.json

As an example, concentrate on the text "green" in the below content..

/* Screen Shield */
.unlock-dialog-clock {
  color: green;
  font-weight: 300;
  text-align: center;
  spacing: 24px;
  padding-bottom: 2.5em; }

screenshot with green text

In your case, the .gresource file you have edited is not used by the lock screen..

For the lock screen, which .gresource or css file is used, varies from your OS rather than simply gnome 3.36

See this answer for further information.
