Just as a matter of interest what brand monitor do you use.

I use a Dell Ultra HDR and also have a LG HDR monitor.
The Dell has the HDR checkbox in the Display Settings.

But the LG needed me to enable HDR using the kscreen-doctor command.

No idea why it claimed the HDR was not disabled and not check box to enable it.

kscreen-doctor is telling me HDR is enabled as well.


sudo kscreen-doctor output.HDMI-A-1.hdr.enable
[sudo] password for steve:

kscreen.doctor: Invalid config.

^C



kscreen-doctor output.HDMI-A-1.hdr.enable
steve@fedora:~$

I issued the command to enable HDR on my monitor via sudo and the command failed. I'm not sure whether it was my monitor or KDE. As shown in the output with the failure kscreen-doctor also did not exit, I had to use ctrl-c to exit. org.kde.kscreen: Failed to request backend: "org.freedesktop.DBus.Error.NameHasNoOwner" : "Could not activate remote peer 'org.kde.KScreen': startup job failed" Interestingly issuing the command without sudo exited without any messages.

You do need to run it as your user.  It needs to talk to the user dbus.

Thanks Samuel, I thought it was updating system components that required root access. Does that mean if it does any updates that they are only active for the current user and if someone else logs into the machine they have to issue the command as well?

regards,
Steve
