Yes! It seems elogind affects the commands in file /usr/share/sddm/ sddm.conf.d/00default.conf to use a different HaltCommand and RebootCommand: $ egrep -i 'Halt|Reboot' /usr/share/sddm/sddm.conf.d/00default.conf # Halt command HaltCommand=/usr/bin/loginctl poweroff # Reboot command RebootCommand=/usr/bin/loginctl reboot Here's a kicker: I do not have '/usr/bin/loginctl' in this (openrc + elogind, but -consolekit, -systemd) system: $ which loginctl /bin/loginctl $ ls -la /usr/bin/loginctl ls: cannot access '/usr/bin/loginctl': No such file or directory $ /usr/bin/loginctl poweroff -bash: /usr/bin/loginctl: No such file or directory NOTE: Running '/bin/loginctl poweroff' from a console works. So perhaps this explains why I also do not have Shutdown/Reboot buttons showing up on the default theme at the top RH corner? Errm ... not so! Please walk through this test case with me: 1. I log out, or reboot. The sddm DM screen shows no Shutdown/Reboot buttons. Consequently, I have no means of shutting down or rebooting from the DM screen. 2. I log out, drop into a console, stop the xdm rc service and restart it. The sddm screen launches and it now presents Shutdown/Reboot buttons as it should! Question: if /usr/bin/loginctl is not present, what commands do the buttons operate/which config file they read, to shutdown/reboot? NOTE: If I login/out, or reboot, the buttons are gone again. :-/ 3. I use KDE's systemsettings 'Startup and Shutdown/Login Screen (SDDM)' to change the default theme. This creates a new /etc/sddm.conf file, with the new Theme entry I selected, but the Halt/Reboot commands are empty. I logout or reboot and the buttons are absent again, or when shown in the new theme they are either greyed out and do not work (Breeze) or not greyed out and still not work. I have not tried setting up a config file in /etc/ and modifying it comprehensively, i.e. specifying my own theme, Halt/Reboot commands, etc., but I do not have a coherent theory why the above behaviour is observed. The next thing to try: I don't have elogind starting up as a boot level rc service, because it is launched when needed by dbus or pam. Perhaps if elogind is running as a background service sddm will (re)launch differently? -- Regards, Mick
