  • Examine this article on the Arch Linux Wiki and follow the procedure to insert the custom background image into the gnome-shellgresource file and change the CSS accordingly.

Origin of the Problem

In versions of RHEL newer than 7.3, visual assets for gnome-shell (and thus GDM) are now compiled into gresource binary files. This includes the background image for the GDM login screen. Bug 1651378 was filed as a feature request for changing this behavior; however, the bug was declined in favor of the login screen rework currently in progres upstream. At the time of writing, it is scheduled to be included in a future version of Rocky Linux 8; however, release dates are subject to change.
