Bug ID: 493066
Summary: Add the ability to choose which display's brightness
level should be controlled by keyboard shortcuts
Classification: Plasma
Product: Powerdevil
Version: 6.1.90
Platform: NixOS
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: general
Assignee: [email protected]

Target Milestone: ---
SUMMARY
Currently pressing keyboard shortcuts changes the brightness level for for all
displays available in the system simultaneously. It may not be a good idea
since every display's brightness range is different, causing the perceived
brightness to be different after pressing the shortcuts
STEPS TO REPRODUCE
1. Use multiple displays
2. Adjust brightness via keyboard shortcuts
OBSERVED RESULT
The brightness level is changed for all displays in the system causing the
perceived brightness level to be different for each display
EXPECTED RESULT
I don't know which option would be better from UX point of view, here are my
proposals:
- Ability to choose which display's brightness is controlled: the active screen
(the screen that was the last one to receive user input), both screens, only
one screen (picked by the user)
- Somehow equalize the perceived brightness level of all displays (maybe it's
possible with the reported HW capabilities and/or using the provided ICC
profiles)
