I ran yum update this morning, getting a gazillion updates. I rebooted the system.
When it came back up, I couldn't log in. I'd get a KDM screen, login, then immediately get the KDM screen again.
I tried to login with a "failsafe" session which gave me (apparently) an xterm that printed black rectangles for all characters :-).
I tried other sessions like xfce and gnome and got the same KDM login screen popping back up after I typed my password.
I got in a vterm as root, created a new user, and logged in as that user with a default gnome session. That seemed to work fine. I decided I should compare what is running in the session with my original user, so I logged out and logged in again as original user, and now my original user login works fine.
Logging in once as a different user appears to have completely fixed the system.
What the heck was that? (It will be interesting to see if the same sequence happens when I install the latest updates at home).
Glad I'm not the only one with a problem! kdm and xfce
I have two workarounds
From Cont/Alt/F2 window as root
systemctl disable kdm.service systemctl stop kdm.service systemctl enable lightdm.service systemctl start lightdm.service OR yum downgrade kdm libkworkspace kgreeter-plugins kde-workspace \ kde-workspace-libs kcm_colors kde-style-oxygen
I will try your solution next
