Configuring SDDM ================ The SDDM configuration file is "/etc/sddm.conf". In that file, you can define the graphical theme to be used among other things. Adding SDDM as graphical display manager for runlevel 4 ======================================================= If you installed SDDM and want this graphical display manager to be used in runlevel 4 instead of Slackware's own KDM, XDM or even Gnome's GDM, then you need to add the following lines to the file '/etc/rc.d/rc.4' directly below the line that says: echo "Starting up X11 session manager..." # ----8<---------------------------------------------------------------- # Use Simple Display Desktop Manager if [ -x /usr/bin/sddm ]; then exec /usr/bin/sddm fi # ----8<----------------------------------------------------------------
