Hi everyone, I tried to set screen backlight through dbus by using the following command on GNOME: dbus-send --session --print-reply \ --dest="org.gnome.SettingsDaemon" \ /org/gnome/SettingsDaemon/Power \ org.gnome.SettingsDaemon.Power.Screen.SetPercentage \ uint32:30 However, I got the following output: Error org.freedesktop.DBus.Error.UnknownMethod: No such method 'SetPercentage' On the other hand, if I switch to Cinnamon, and replace everything ``gnome" above with ``cinnamon", as following: dbus-send --session --print-reply \ --dest="org.cinnamon.SettingsDaemon" \ /org/cinnamon/SettingsDaemon/Power \ org.cinnamon.SettingsDaemon.Power.Screen.SetPercentage \ uint32:30 The backlight is changed: method return sender=:1.9 -> dest=:1.58 reply_serial=2 uint32 30 I suspect this is some abandoned method to change backlight, but I cannot find any official document. Can anyone help me with this? Thanks, Hong
