Bug ID: 504965
Summary: Allow disabling software dimming of screens
Classification: Plasma
Product: plasmashell
Version First master
Reported In:
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: Power management & brightness
Assignee: plasma-b...@kde.org
Reporter: zocker.netw...@gmail.com
Target Milestone: 1.0
SUMMARY
I like KDE’s new approach to dim multiple screens together. However, I dislike
that the output to my TV is software-dimmed (because it does not support
DDCCI). Especially because this makes the image quality on the TV worse than
required, and also because earlier it was possible to quickly dim down the
laptop screen to save battery while the content on the TV continues to play.
But also on my PCs and other outputs, I would like to disable software dimming
just because I would rather like to change it manually on the screen to
preserve quality.
STEPS TO REPRODUCE
1. Have a laptop with an integrated screen
2. Connect a TV (or other non-DDCCI capable screen)
3. Dim down brightness with special keyboard keys
OBSERVED RESULT
Starting from a certain step, the brightness of the TV goes also down, but that
is obviously emulated in software.
EXPECTED RESULT
Only dim the laptop screen and do never dim in software-emulated (as option).
