Hi, Thanks for the helpful response, Tom. [Re: KDE system settings]
However, I also see "You are note allowed to save the configuration".
That's odd. It works fine for me. You should see a key icon next to the Apply button, and when you click it you will be asked for the root password.
Hmmm. I don't have any such key icon. The apply button is just greyed out.
I'm afraid I also don't know how KDE system settings panels are supposed to request root permissions to allow settings like this.
This is done via policykit.
Would I need some optdepend installed or some daemon started to make this work? I notice that I have polkit-qt installed, but I don't think I've ever done anything explicit with regard to policykit. I'm in the wheel group, in case that matters. I'm running [testing] on this machine. Perhaps that could cause the difference? Pete.
