Solus confuses function keys on HP Probook 455 G5

Sphor

My machine is

System:
Kernel: 5.4.12-144.current x86_64 bits: 64 compiler: gcc v: 9.2.0
Desktop: Budgie 10.5.1 info: budgie-panel wm: budgie-wm dm: LightDM 1.30.0
Distro: Solus 4.1
Machine:
Type: Laptop System: HP product: HP ProBook 455 G5
CPU:
Topology: Dual Core model: AMD A9-9420 RADEON R5 5 COMPUTE CORES 2C+3G

and it seems to believe that the Brightness-Up (under f4), Brightness-Down (under f3) and Mute-Microphone (under f8) buttons are all the same button.
In Settings, I have tried to make a Custom Shortcut, but before looking into what command it is that I should use (xbacklight is not working even though it does not return any error, but it plainly doesn't work), I first checked to see if it allows me to use that button, and unfortunately no.

Brightness doesn't show in the Power section of the Menu either, so I cannot adjust it there.

I have run gsettings list-recursively | grep media-keys
and it provided the following:

localectl gives me the following:

   System Locale: LANG=en_GB.UTF-8
       VC Keymap: n/a
      X11 Layout: gb
       X11 Model: pc104

And xmodmap gave me this:

xmodmap:  up to 4 keys per modifier, (keycodes in parentheses):

shift       Shift_L (0x32),  Shift_R (0x3e)
lock        Caps_Lock (0x42)
control     Control_L (0x25),  Control_R (0x69)
mod1        Alt_L (0x40),  Meta_L (0xcd)
mod2        Num_Lock (0x4d)
mod3      
mod4        Super_L (0x85),  Super_R (0x86),  Super_L (0xce),  Hyper_L (0xcf)
mod5        ISO_Level3_Shift (0x5c),  Mode_switch (0xcb)

It's just an inconvenience more than anything, as the machine overall seems to work, but I thought it might be worth pointing out, and it would definitely make me happier if I could adjust my laptop's brightness like I can in Windows.

before anything else, i suggest that you update your machine. 5.4 is somewhat an old kernel. budgie is outdated too.

use sudo eopkg up - y

Hmm, I have run sudo eopkg up -y several times since the install date, is there any other way I should try?
I remember Manjaro had a specific tab only for Kernels to move up & down as needed, is there something similar in Solus?

Sphor is there any other way I should try?

well, using terminal for updating is the recommended move, but you can use software center to update too. unfotunately, i had trouble updating my system with SC so these days i only use it for seeing the changelogs.

but what surprises me is that you are still running solus 4.1( clearly shown on the logs you posted). now forget 4.2, even solus 4.3 released several months ago. and maybe 4.4 could be upcoming!!

Oh my, you're right to be surprised, it seems that was the output of my 1st install, not the 2nd one

I did not have time to make this post in 1 go, so I used Telegram to save the output for later; I must have mixed them up.

Here's the actual current output:

System:
  Kernel: 5.14.16-205.current x86_64 bits: 64 compiler: gcc v: 11.2.0
  Desktop: Budgie 10.5.3 info: budgie-panel wm: budgie-wm dm: LightDM 1.30.0
  Distro: Solus 4.3
Machine:
  Type: Laptop System: HP product: HP ProBook 455 G5 v: N/A serial: <filter>
  Chassis: type: 10 serial: <filter>
  Mobo: HP model: 8370 v: KBC Version 03.2B.00 serial: <filter> UEFI: HP
  v: Q84 Ver. 01.17.00 date: 08/10/2021

I will also change the initial one, so people don't have to read this embarassing mix-up on my side

P.S.
Nevermind, apparently once someone replies, it cannot be changed anymore (I think?)

Sphor Nevermind, apparently once someone replies, it cannot be changed anymore (I think?)

Correct, as soon as someone replies to a post, you can't change the post anymore. Only mods/admins can edit them after that.

I have done nothing in particular, just kept updating the system every once and again, and it seems to have sorted itself out.
I'm unsure what it is in particular that did it, however: I've done no additional tweaking other than running sudo eopkg up -y at least monthly. (I don't use this laptop often because although portable and with a decent battery compared to what I'm used to, its processor is very weak and makes the majority of tasks tedious.
