Why choose Netrunner and the vanilla KDE, to dark my Display after x minutes by default ?
Even, when the power supply is plugged in…?
I don’t know about the Kubuntu based edition but the Manjaro based rolling edition’s power management on battery is set to a ridiculously long time by default. I think maybe the acpi drivers are not working with your hardware / bios properly.
Maybe the configuration files in KDE SC 4.13.1 changed again. I will check that.
