Description Jared Van Leeuwen 2023-08-07 14:21:03 UTC

SUMMARY
***
I will start the slideshow, but after two minutes the monitor powers off due to lack of user activity. Instead of messing with my power settings every time I want to play a slideshow, digiKam should call win32 SetThreadExecutionState(ES_DISPLAY_REQUIRED | ES_CONTINUOUS); every minute the slideshow is playing.
***


STEPS TO REPRODUCE
1. Set monitor to power off after a short period of time (2 minutes)
2. Start a digiKam slideshow that will last longer than the monitor power off.
3. 

OBSERVED RESULT
Monitor power's off before the end of the slideshow.

EXPECTED RESULT
Slideshow reaches the end before monitor powers off.
