[Bug 1967014] Re: Lenovo Ideapad 3 screen brightness F keys not working...

[Jaymz]

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"

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

Status in systemd package in Ubuntu:
  Incomplete

Bug description:
  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.
