[SOLVED] Brightness keys only work on reboot

Since a few weeks I’ve been having issues with the brightness keys, and only the brightness keys. When the issue is happening, the brightness - and + don’t react. The other media keys such as play, pause, mute, volume - and + work fine.

It’s similar to the issues described in this thread: [SOLVED] 13th Gen Intel Framework 13 running Fedora 38, media keys aren't working

Currently I have kernel 6.3.12-200. I’m using Fedora 38 with the 12th gen Intel. While it was happening, I checked if the module was blacklisted properly. I checked my / proc / cmdline to check if it did boot with the module blacklisted:

cat / proc / cmdline
BOOT_IMAGE=(hd0,gpt2)/vmlinuz-6.3.12-200.fc38.x86_64 root=UUID=00000000-0000-0000-0000-000000000000 ro rootflags=subvol=root rd.luks.uuid=luks-00000000-0000-0000-0000-000000000000 rhgb quiet nvme.noacpi=1 module_blacklist=hid_sensor_hub

Showkey doesn’t show anything for the FN brightness - and + keys when it happens.

The strange thing is, this only seems to happen on a cold boot. When I reboot using the reboot command then the keys work again. If I then proceed to shutdown completely shutdown -h now and then press the power button to boot up again, the media keys don’t work.

Could anybody help be debug this issue?

Showkey shows nothing at all, as if no key was even pressed? I’m not certain, but it seemed as if Showkey registers keypresses at a low level. Even for keys that aren’t configured, you still get a scan code.

~edit~
evtest was what I was thinking of, rather than showkey.

How about evtest, does it register?

sudo apt install evtest
sudo evtest

Then press 2, then try pressing the keys

No reaction at all, here is an overview of when I pressed fn-F1 up until fn-F12. You can see that after KEY_NEXTSONG it goes straight to KEY_P.

It looks like the brightness keys still don’t show up, but they work now. Let’s just check showkey again, and it shows:

showkey
kb mode was ?UNKNOWN?
[ if you are trying this under X, it might not work
since the X server is also reading /dev/console ]

press any key (program terminates 10s after last keypress)...
keycode  28 release
keycode 224 press
keycode 224 release
keycode 225 press
keycode 225 release
keycode  29 press
^Ccaught signal 2, cleaning up...

That’s odd, have you tried with live distro and retest with evtest?

Same thing, brightness keys don’t work from a fresh Fedora 38 live image:

On this one: Linux localhost-live 6.2.9-300.fc38.x86_64 #1 SMP PREEMPT_DYNAMIC Thu Mar 30 22:32:58 UTC 2023 x86_64 GNU/Linux

Going to try rebooting into the live image (doing reboot and immediately pressing F12 to boot straight into the flash drive again) to see if they’ll work then. Edit in 2-3 minutes.

Edit:
That still didn’t work! No brightness keys.

I realized I’ve been testing with the live media wrong. I can properly reproduce it with the live image now. I forgot to append the module blacklist to the boot parameters. So what I did now:

  1. Press F12 to get into boot mode
  2. Select flash drive with live image of Fedora 38
  3. Press E in grub, append module_blacklist=hid_sensor_hub to kernel options, F10 to boot
  4. Brightness keys don’t work
  5. Send reboot command
  6. Press F12 to get into boot mode
  7. Select flash drive with live image of Fedora 38
  8. Press E in grub, append module_blacklist=hid_sensor_hub to kernel options, F10 to boot
  9. Brightness keys do work

Evkeys (only brightness, then CTRL-C) of step 9):

So in conclusion, this issue persists over the live image.

I Wonder if behavior persist on Ubuntu 20.04 and 22, as well in fedora 37?

I just loaded ubuntu-20.04.6-desktop-amd64.iso on a flash drive and repeated everything I did earlier, including appending the module_blacklist during boot, and got the same results.

That means this happened again:

  1. Press F12 to get into boot mode
  2. Select flash drive with live image of Ubuntu 20.04
  3. Press E in grub, append module_blacklist=hid_sensor_hub to kernel options, F10 to boot
  4. Brightness keys don’t work
  5. Send reboot command
  6. Press F12 to get into boot mode
  7. Select flash drive with live image of Ubuntu 20.04
  8. Press E in grub, append module_blacklist=hid_sensor_hub to kernel options, F10 to boot
  9. Brightness keys do work

This is starting to look like some hardware issue, isn’t it? :frowning:

Hi @Username009,

Yes looking like a hardware issue, are you still under warranty? might be worth opening a ticket. :slight_smile:

I think have the same issue with my device. core-i7 1360p running Ubuntu 23.04.

evtest does not show key presses for f7, f8, or f10, but they work until I put laptop into sleep mode. If it goes into sleep mode, those functions no longer work.

Since the functions work before going into sleep mode, it seems to me like it shouldn’t be a hardware issue?

My evtest output which looks similar to the others here:

Just trying to get related info, what does xinput look like on your system?

sudo xinput --list

If anybody is interested in an update, I’m still talking to support.

So far have I received a replacement input cover, but the issue still persists. It seems like a hardware issue somewhere else for now.
