One of the traditional components of any Linux distribution is the session manager, that the draft has been GDM GNOME and that is KDE KDM. Made the leap to Ubuntu LightDM months ago, but yet many distributions still using GDM as the component that provides these benefits.
For that reason I think it’s good idea to offer a few items that will allow you to customize GDM this session manager in various ways. The effort is not really mine, but the web where Ubuntu.ka have collected dozens of themes for GDM , which I have simply moved to MuyLinux for ye more accessible. These themes, so enjoy!
