Login screen for F40

[Michael Eager]

I recently upgraded to F40 (KDE) and, for the most part, everything is 
working.  Except the login screen.

I've tried to install slick-greeter and lightdm-gtk-greeter, following 
whatever recommendations I found online.  The result is a hung system 
with a black screen until I remove the greeter configuration and reboot.

Can someone point me to a reasonable login screen and configuration?

I had a bad upgrade a couple of years ago. I had to install/reinstall
the following for KDE on Fedora.

* sddm (reinstall)
   * kde-style-breeze (install)

And I had to remove this to get rid of the Soft Input Panel/Virtual
Keyboard. I installed it after things broke, but it was not needed:

* gtk3-engines-breeze

Checking my F40 machine, it looks like sddm is still being used:

$ sudo ps -A | grep -i sddm
  1450 ?        00:00:00 sddm
  1621 ?        00:00:00 sddm-helper

You don't say what DE you're using. The recommendation for KDE is SDDM.

From sddm(1):
       sddm runs the greeter as a system user named sddm whose home
directory needs to be set to /var/lib/sddm.

What features are you looking for that the default SDDM does not provide?

Most of my F39 Plasma installations use KDM. None use SDDM. A few use TDM. IIRC,
none of my F40 installations have Plasma (or SDDM, or GDM, or LightDM) installed.
KDM is still showing as available in F40. Mine not using KDM are using TDM.

Thanks all who responded.

When I upgraded to F40, SDDM was not installed.  LightDM was installed. 
Somehow I had the impression from the release notes that SDDM was no 
longer available.  That seems to be incorrect.

I'll take a look at KDM or reinstall SDDM and go back to what I've been 
doing for ages.

FYI: A fresh install of KDE plasma f40 will setup SDDM for you.

SDDM is the recommended DM for KDE. IIRC KDM is deprecated.
