The startkde script does this # At this point all environment variables are set, let's send it to the DBus session server to update the activation environment if which dbus-update-activation-environment >/dev/null 2>/dev/null ; then dbus-update-activation-environment --systemd --all else /usr/lib64/libexec/ksyncdbusenv fi but without user-session USE flag on dbus, I get this error in SDDM xorg-session.log dbus-update-activation-environment: warning: error sending to systemd: org.freedesktop.DBus.Error.Spawn.ChildExited: Process org.freedesktop.systemd1 exited with status 1 and the DBUS_SESSION_BUS_ADDRESS is not set when launching terminals inside Plasma. For many applications this would be fine because they can still find the session bus via ~/.dbus/session-bus. google-chrome however will refuse to connect to session bus because of another bug [1] if this environment variable is not set. As a result, playing videos in chrome will not inhibit screensaver (because that's done via session bus). Rebuild dbus with user-session flag seems to fix this problem for me. It seems Debian hits the same thing [2]. Perhaps we could add a new RDEPEND "systemd? (sys-apps/dbus[user-session])" to plasma-workspace?

Thanks for your detailed bug report! Since 5.10.5 is already stable, I've targetted this for the next versions via KDE overlay.
Great. Thanks!
This is in tree with 5.11.0 now.
