Package: libkf5screen-bin Version: 4:5.8.4-1 On KDE startup and then periodically I get a huge burst of
org.kde.KScreen[1167]: kscreen.xcb.helper: RRNotify_OutputProperty (ignored) org.kde.KScreen[1167]: kscreen.xcb.helper: Output: 67 org.kde.KScreen[1167]: kscreen.xcb.helper: Property: Backlight org.kde.KScreen[1167]: kscreen.xcb.helper: State (newValue, Deleted): 0 messages in the user journal log. The severity is warn and the PID is from dbus-daemon -session I couldn't find a way to limit these logs w/o also limiting system messages. In the dbus sources though I saw that the stdio from the spawned processes is apparently forwarded to the syslog. So I ended up changing the /usr/share/dbus-1/services/org.kde.kscreen.service to [D-BUS Service] Name=org.kde.KScreen Exec=/bin/sh -c '/usr/lib/x86_64-linux-gnu/libexec/kf5/kscreen_backend_launcher >/dev/null 2>/dev/null' which indeed helps. IMHO kscreen should log these warnings once. Best regards, Koos Vriezen
