Everyone agrees that kdm sucks and finally there's a pretty replacement. Too bad it's not build for gentoo so could anyone please build a ebuild for it? Should be a 5 min job. Thank you! Reproducible: Always Steps to Reproduce: 1. 2. 3.
As far as I am aware, mdm (the display manager you want) is missing a lot of the functionality (e.g. networking) that kdm has. It also doesn't seem to be actively developed anymore. However, it still may be great for many people. I too would be interested in an ebuild, just to try it out. Also, some KDE developers are working on the ability for the normal kdm to support gdm themes natively. See: http://webcvs.kde.org/cgi-bin/cvsweb.cgi/kdenonbeta/kdmthemes/
Last upstream release (0.0.3) 2+ years ago, no ebuild attached here either. WONTFIX.
