Lenovo Ideapad 3 screen brightness F keys not working...

[Jaymz]

As the title says, the F keys the control screen brightness (F11/F12 on the Lenovo Ideapad 3 15ITL05 laptop I have) don't work on Ubuntu 21.10. All other special function keys (volume up/down, lock screen, airplane mode, etc...) and the screen brightness slider in the top right-hand corner work; it's just the brightness keys that are not working.

I know I can just use the slider, but it's more convenient to use the F keys. I hope you are working on this for a future 21.10 update.

Also, I originally installed 20.04 and upgraded to 21.10, but even on 20.04, those keys weren't working, either.

Are you still running Focal, or have you tried upgrading to Jammy (or another release)? If this is still an issue on whatever release you are running, can you please run:

$ sudo evtest

and when prompted, select device number that corresponds to your keyboard. Then, press the key combination that you expect to adjust brightness up, and then the same for brightness down, and attach that output?

Please also attach the output of:

$ udevadm info /dev/input/eventX

where X is the same number selected in the evtest command, and the output of:

$ cat /sys/class/dmi/id/modalias

I'm on 22.04.2 LTS now, not sure what kernel, but the brightness F-keys still don't work.

I tried sudo evtest in terminal, but it says "sudo: evtest: command not found"
