--- Comment #13 from Martin Bříza mbriza@redhat.com --- Neal, using the following command (as root): systemctl enable --force sddm.service will replace your current DM with SDDM. On the next reboot, you'll get SDDM. If you won't want to reboot, switch to an other VT ([Ctrl + Alt + F6] for example), log in as root and use the following commands: systemctl stop display-manager.service # this will switch you to VT1, most probably, so then switch to VT6 again with [Alt + F6] systemctl start sddm.service I have described some basic steps on how to test the package on https://fedoraproject.org/wiki/Changes/SDDMinsteadOfKDM . However, many of the steps don't apply, as some needed features aren't implemented yet in this version.
