Fedora 13 Login Screen

[amithad]

Hi,

I tried installing Login Screen themes using system > preferences > appearance on GNOME 2.30.0 by clicking on get more themes online and selecting login window category in art.gnome.org site.

But when I try to download and install it it open with default archive manager but not with theme installer

By trying downloading the theme and installing it both by raw archive format and extracted format gives the error

<theme name> does not appear to be a valid theme

At that there is no login screen customization option in system > preferences

Is there any alternative?

thanks
