In case you are using an external monitor, you’ll have to use the buttons on the monitor to change the brightness. Under the Brightness and Color Menu, move the slider to the left to make it dimmer, or move it to the right to make it brighter. Open Settings on Windows 10 and navigate to System> Display. Here’s the list of all methods we will be following to adjust the screen brightness manually: There are many ways of adjusting the screen’s brightness manually, including some options to adjust it from settings, action center, and more.

I do think it would be nice that when one installs GNOME it asks whether you want to assign some particular keys to such action when no dedicated key with the proper marking on it is detected (i.e. There is already an issue opened for your particular issue of not having those shortcuts included in the Settings, so maybe you can give your use-case there and some informations on e.g. Now, there probably needs to be some limit to the amount of shortcuts that should be included in the UI, some kind of rule, but this particular one seems sensible enough. Since the settings app already allow changing the keyboard shortcuts for volume up/down, I don’t see a reason why it could not include brightness up/down too. For example, gsettings set .media-keys screen-brightness-up "" will make the = key toggle the brightness up. In any case, even if changing the brightness key is not available in the keyboard shortcuts settings, they are still accessible by changing the gsettings key (which are all listed with gsettings list-keys .media-keys), and here the gsettings keys you’ll need to change are screen-brightness-up and screen-brightness-down. ![]() Hence it is not your call to .Screen.StepUp which triggers the OSD, but it’s the media keys daemon itself, so that’s why you’re not seeing the OSD. Variant string "display-brightness-symbolic"Īt the beginning a dbus signal is sent to destination 1.58 here (to the media keys daemon, as checked in d-feet) from GNOME Shell (1.16), and in the later two method calls you can see it’s the media keys daemon (1.58) which asks to the settings daemon to change the brightness, and which also asks GNOME Shell (1.16) to show the correct OSD. Method call time=1645539568.612719 sender=:1.58 -> destination=:1.61 serial=88 path=/org/gnome/SettingsDaemon/Power interface=.Screen member=StepUp If you open dbus-monitor -session then press the brightness key, it’ll give you something like this:ĭbus-monitor output log signal time=1645539568.611688 sender=:1.16 -> destination=:1.58 serial=1740 path=/org/gnome/Shell interface= member=AcceleratorActivated This is because it’s not the settings daemon that sends a request to show the OSD, it’s GNOME Shell itself when it notices a brightness up/down key press. This works, however the OSD is not triggered. ![]()
