Description Dave Flogeras 2016-01-01 18:30:28 UTC

This may be by design, but if I set a 1 minute timeout to lock my session automatically it works as expected.  If I uncheck the "Enable Power Management" in the system tray (by clicking the battery icon first), the timeout no longer applies.

I would expect the power management uncheced to prevent the monitor from sleeping, and/or the machine from suspending/hibernating, but do not expect the lock time to be affected.  If this is by design, just close it.

Tested on 5.4.3 machine.

Reproducible: Always

This is intentional. When watching a video you want neither your screen turn off, nor have it lock. We're currently discussing a possible solution for this problem.

May I ask why you uncheck this checkbox in the first place? Is it some application not properly blocking power management when you would expect it to (presentation, video playback, etc)?

I only noticed when testing https://bugs.kde.org/show_bug.cgi?id=357368

I thought it may be unintentional, but when you explain it as above (for uninterrupted presentation/video watching) it makes complete sense to prevent the idle timeout.  My gut feeling was incorrect. Sorry for the noise :)
