Note: when renaming the .desktop file, it may automatically be renamed to "MdmGreeterTheme.desktop.desktop" - if that happens, use the terminal to rename it to "MdmGreeterTheme.desktop" (a single .desktop) using the "mv" command.
This is completely obtuse. It does not say where this mysterious fle is or why these changes are needed, It also does not explain how to add themes.
This is no longer the case. Recognizing the fact that GDM themes are very numerous already and that the current GDM isn't themeable, recent versions of MDM work with GDM themes.
So the file should be GdmGreeterTheme.desktop and it should contain a [GdmGreeterTheme] section.
I downloaded a theme from Gnome-Look.org that is already in MDM format (file already named MdmGreeterTheme.desktop). However, it was hosted on DeviantArt, and downloads as a .zip file. I uncompressed the file, and recompressed it to .tar.gz. MDM Setup says the following:
Not a theme archive
File not a tar.gz or tar archive
Great tutorial - a very easy way of customising MDM.
