Here is the question:
Recently I installed the ubuntu 11.04.I still use the classic gnome desktop environment with the gdm(version:2.32) login manager. and I want to change the login screen with the cool login theme at the gnome art and install the gnome-art tool to install login manager themes from it. Unfortunately, its install button is gray. why ? howto ?
I just cannot fix the core of the question. According to many advices, I used some other configure tools like gnome tweak, and gdm tweaker, gdmsetup and so on. however,some of them just can change the login background with a picture, what I really need is how to install the login manager themes file(.tar.bz2 format) from the gnome art web.
I don't know weather you have understood it ? every answer is welcome.
