Wacom One brightness linux
Raw
wacom one (2020) registers.md

A quick reference for setting the display for Wacom One on linux using ddcutil/ddccontrol

0x0b, 0x0c color temp increment and temp request (i have no idea how to use that, but default is good) 0x10 (black level), keep it on 50 0x12 contrast, keep it on 50 (probably)

0x6b brightness (backlight), default: 50, max 100

Gamma can't be configured, mine tablet has sRGB gamma (what I would expect from any sane graphics tool)

How-to use these?

Install ddccontrol ddccontrol -r 0x6b -w 50 dev:/dev/i2c-1 // Assuming your tablet has i2c-1 and you want to set brightness to 50%
