From Bugzilla Helper: User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.2-2 i686) Description of problem: I can't run WindowMaker as my manager because gdm doesn't see it How reproducible: Always Steps to Reproduce: 1. Just install WindowMaker, run gdm. Actual Results: WindowMaker wasn't included in window-manager list Expected Results: I'd expect to see WindowMaker in gdm managers' list Additional info: I have fixed the problem by adding the file: /etc/X11/gdm/Sessions/WindowMaker #!/bin/bash exec /etc/X11/xdm/Xsession windowmaker but I think the similar file should be included in WindowMaker rpm file.
