SUMMARY Currently, disabling the "Turn off screen" option also disables the "When locked, turn off screen" option. These two options should be separate because a user may only want his screen to turn off when he manually locks the screen. STEPS TO REPRODUCE 1. Go to System Settings -> Energy Saving 2. Go to any power profile 3. Uncheck "Turn off screen" OBSERVED RESULT "When locked, turn off screen" is disabled EXPECTED RESULT "When locked, turn off screen" should not be disabled SOFTWARE/OS VERSIONS Operating System: Arch Linux KDE Plasma Version: 6.0.4 KDE Frameworks Version: 6.1.0 Qt Version: 6.7.0 Kernel Version: 6.8.9-arch1-1 (64-bit) Graphics Platform: Wayland Processors: 16 × AMD Ryzen 7 6800U with Radeon Graphics Memory: 30.7 GiB of RAM Graphics Processor: AMD Radeon Graphics Manufacturer: HP Product Name: HP EliteBook 845 14 inch G9 Notebook PC
Came here to report the same thing. My use case is that I want to monitor a long-running process by glancing at the screen, without the screen turning off. But if I manually lock the session, I *would* like the screen to turn off after a short while. I am using Plasma 6.1.4 and the above instructions are now: STEPS TO REPRODUCE 1. Go to System Settings -> Power Management 2. Go to any power profile 3. Set "Turn off screen" to Never OBSERVED RESULT "When locked" dropdown is disabled EXPECTED RESULT "When locked" dropdown should not be disabled
