Bug ID: 470453
Summary: Feature Requests: Add support for keyboard backlight
brightness cycle, color cycle and brightness changed
key
Classification: Plasma
Product: Powerdevil
Version: unspecified
Platform: Other
OS: Linux
Status: REPORTED
Severity: normal
Priority: NOR
Component: general
Assignee: plasma-b...@kde.org
Reporter: w...@tuxedocomputers.com
CC: m...@ratijas.tk, natalie_clar...@yahoo.de
Target Milestone: ---
The old three KEY_KBDILLUM* keycodes don't reflect the current situation
modern notebooks anymore. Especially the ones with RGB keyboards.
e.g.
- Clevo NL50NU has a toggle, an up, a down and a color-cycle key
- TongFang PH4ARX1 doesn't have a toggle key, but one that cycles through
off, half-brightness, and full-brightness.
Also, on some devices these keys are already implemented in firmware. It
would still be nice if there is a way to let userspace know when one of
these keys is pressed to display the OSD, but don't advice it to actually
do anything. This is the intended purpose of the KEY_KBDILLUMCHANGE define.
My draft sent to the LKML:
https://lore.kernel.org/all/20230530110550.18289-1-...@tuxedocomputers.com/
Is there interest in this besides me? What are other potential keys?
