I've extracted the files to their directories and copied them into /usr/share/themes, but none of the drop downs in the Appearance tab in Gnome-tweak-tool show any of the new themes. Is /usr/share/themes to location for GDM themes?
Based on the above, and Samuel's response to the thread: Are you trying to change the theme of the login screen?
If so, then you can't, generally, change that with any user configuration tool. They, usually, configure *your* session (after you've logged in). The login screen is managed differently.
(At least it used to be) to configure the GDM login, you need to adjust the GDM user's settings (which you can't), or manually adjust the files that it will use (change the XML file, and change the graphics files it refers to). That's what I had to do the last time I customised the login screen.
Supposedly you can issue gconf commands to the gdm user's settings, but I never got that to work.
Years ago, it became yet another of those things that Gnome stopped letting you adjust. The old methods for changing the GDM screen stopped working, and even the gdm.conf config file doesn't do what it used to.
