Keychron keybord lost backgroundlight after login into plasma 6.7

Help
1

I’m running EndeavourOS.
After updating to Plasma 6.7, I noticed the following issue: As soon as I enter my password in SDDM and it switches to Plasma, my backlight goes to blue/white. Normally, my backlight is set to red. It stays red until I make an entry in SSDDM.
I’ve already logged in using Ctrl+Alt+F3 and run this command:
dbus-run-session startplasma-wayland
Same behavior.

  • Keychron K3 Pro
  • USB-ID 3434:0231
  • Arch/EndeavourOS
  • Plasma 6.7
  • Wayland
  • reproducible with dbus-run-session startplasma-wayland
  • The problem does not occur during bootup, but specifically when the Plasma session starts.

There’s already a thread about this on KDE Bugs.

Do you see this in the “Brightness” widget on the system tray?

If so, try disabling “Follow accent color”?

Yes I have tried it. Off and on.

EDIT: I am such stable genius. After deactivated I have to reset my keyboard and everything is fine. Thank you @pg-tips
