Switching to SDDM

[Patrick O'Callaghan]

I just upgraded to F21 via the "nonproduct" route, and I find KDM is
still my default desktop manager. Can someone remind me how to switch to
SDDM? I know it's a FAQ and I should remember :-)

You could try
# systemctl disable kdm
# systemctl enable sddm

That did the trick, thanks. I was used to editing config files to get
this to work.

There's also something called system-switch-displaymanager, I think.

Not on my system. Maybe it's part of the Workstation "product".

You have to install the package system-switch-displaymanager-gnome.

Doesn't work on my system, all I get on reboot is a black screen.

No errors in /var/log/messages, /var/log/sddm.log, or /var/log/Xorg.0.old.

Did you mean to ask if sddm is installed?  kdm is what I've been using.
sddm-0.10.0-2.fc21.x86_64

Again, no error messages.

No meant to ask if kdm was installed but I read your question backwards. 
So disregard. :-)

There is a bug with SDDM that means the first time you try to log in you
get the failsafe KDE session. You have to select normal KDE on the login
screen, then subsequent sessions will work correctly.

I can't see how this would produce the problem you're seeing, but just
so you know.
