Description tuxuser 2023-01-15 14:19:19 UTC

System: Lenovo ideapad 3
OS: openSUSE Leap 15.4, all updates installed
Kernel: 6.1.5, 5.14.21-150400.38-default

Brightness keys are not working. When pressing these in kde plasma no brightness increase / decrease indicator is shown.
The brightness system itself is working: When changing the brightness using the plasma battery applet, the brightness changes as expected.

Changing to runlevel 3 showkey and evtest don't respond to pressing these keys. They only respond to other keys.
evtest displays
/dev/input/event1 is Video Bus
Here it displays Event code 224 for KEY_BRIGHTNESSDOWN and Event code 225 for KEY_BRIGHTNESSUP. But pressing the buttons leads to no response.

This turned out to be the same issue as bug 214899.  6.2-rc kernel works fine.
