I upgraded my system from FC21 to FC 22 KDE and it is using KDM as a login window. I think this is a reminiscence from previous upgrades.

I also installed other system with FC22 from scratch and there is no kdm installed and login window is different

What do I need to do to replace KDM login with the one used by default in FC 22 KDE (whichever it is) ?

Just found what I was looking for

It seems Fedora 22 uses sddm as default login manager (at least for KDE) and we can easily switch between login managers by using systemctl like these examples:

sudo systemctl disable kdm.service
sudo systemctl enable sddm.service


sudo systemctl disable sddm.service
sudo systemctl enable kdm.service

KDM is retired. SSDM was already foreseen for F21:

  • install group package

    dnf groupinstall KDE

  • check if there is missing package for kdm

    dnf install kdm kde-settings-kdm

    dnf install system-switch-displaymanager.noarch

  • switch

    system-switch-displaymanager KDM

    this should do the trick

Hi, I think you did not understood my question

I don't want to switch from GDM to KDM or viceversa

I think there is some new Login Manager in FC22 and I would like to know what it is

I have a FC22 installed from scratch and it does not has gdm or kdm installed, so there has to be some other new Login Manager in FC 22.
