For years now, I have been clinging to xdm as my display manager; years ago, I spent several days tweaking the configuration files of xbanner and xdm to get it to look “just so”, and I didn’t want to change it. But no more! After my last upgrade predictably broke my xdm and xbanner configuration, I decided to spend a little time trying to get each display manager to look “right” with my original login screen design. Pleasantly, both gdm and kdm are much easier to customize, and I had something tolerable with each in less than an hour. I found that kdm was more flexible and gave me much closer to what I was looking for, while gdm was quite obstinate about appearances, though it may be slightly more capable technically.
