i think that was it, thank you! I must have enabled smart contrast which does that.

the classic cronjob workaround works great.

The command /usr/bin/openrgb --profile /home/user/.config/OpenRGB/test.orp runs fine, loads the test.orp setting i saved with openrgb-GUI. Until the keyboard goes back to default after 4 min or so.

Therefore i made a cronjob that does the same, just every 3 minutes: */3 * * * * /usr/bin/openrgb --profile /home/user/.config/OpenRGB/test.orp

correction: nevermind it does not work. Again. They keyboard just resets itself after like a minute, regardless. Don’t understand what is happening.

It works fine now. Uninstalled the openRGB flatplak from the kde neon app store (discover) and instead installed the .deb from the openrgb-website. Now it works with static dimmed LEDs. NICE!
