I have been searching how to install gdm themes from websites like customize.org/ggdm in backtrack 5 r3 gnome for some time now. I've tried different methods and all i have managed to do was to change the background and color. In Ubuntu or Debian there is is a login window gui that allows you to install gdm themes. So i was wondering if there is a way to get this in backtrack or if there is another way to install gdm themes. Thanks in advance.
