Brightness controls, a different behaviour between dragonized and qtile garuda distribution

brightness controls

different behaviour between dragonized and qtile garuda distribution

hi guys :slight_smile:
I just recently switched from garuda dragonized version to qtile version since i want to start a little bit more customization.
the installation was flawless as always but i encountered a bit of a different behaviour in qtile version

the issue

basically the brightness keys, the volume keys and the multimedia keys of my laptop are not working since i installed the qtile version (they did work on the dragonized one)

what i tried

i tried opening qtile config under ~/.config /qtile in search for the keybindings and i found them (i'll take brightness ones as an example but i did it with the multimedia controls too)

Key([], "XF86MonBrightnessUp", lazy.spawn("xbacklight -inc 5")),
Key([], "XF86MonBrightnessDown", lazy.spawn("xbacklight -dec 5")),

so i started checking if it was a problem related to XF86MonBrightnessUp ecc... not correctly detecting the keypress by manually changing them to other keybinding:

 Key([], "F2", lazy.spawn("xbacklight -inc 5")),
 Key([], "F3", lazy.spawn("xbacklight -dec 5")),

this didnt resolve it (i tried even simpler key combination like mod 2 ecc...) so i thought about trying the xbacklight command in the command line to check if it works
i tried these 3 commands

xbacklight -inc 5
xbacklight -dec 5
xbacklight -set 50

sadly still no effect.


At this point i am not sure how to proceed and a bit confused, does Dragonized and Qtile versions use different commands to achieve backlight and multimedia controls? Am i missing something?
i am a bit curious about the difference.

As always thank u all in advance :slight_smile:

Was the "working configuration" on the same kernel version?
I remember reading someone having troubles with brightness in kernel 5.15.
Could it be that the Dr460nized was before?
Maybe you could try installing the linux-lts now on qtile.


hi, i tried switching the kernel to linux-lts but it didnt resolve it.

You were right about the kernel difference tho, i checked zen versions and they were different 5.14.8(dragonized) 5.15.2(qtile current)

Sorry, don't know much about qtile. We'll need someone more experienced.
If it was only e.g. about brightness, maybe it could worth digging somewhere, but since this occurs also for multimedia controls there must be some explanation.
For brightness e.g. I was checking here that brightnessctl could help to add udev rules to allow members of the video (or input) group to modify brightness, due to something I read here.
Also this could be an idea, but it is not specified with which cards it can help.
We'll see... Good luck!


actually i just tried brightnessctl and it works!!
i changed the keybinds to :

    Key([], "XF86MonBrightnessUp", lazy.spawn("brightnessctl s +5%")),
    Key([], "XF86MonBrightnessDown", lazy.spawn("brightnessctl s 5%-")),

and now they work perfectly

i will still try to search for how to adjust the multimedia and volume keys :slight_smile:

quick edit: i forgot to mention i had to install it by sudo pacman -S brightnessctl




It might be worth implementing this in the default config if its universally applicable? @RohitSingh :thinking:


Maybe give a look here...

I just find out the problem with the audio keys
the problem was that the


package was not installed but it was called by

    Key([], "XF86AudioMute", lazy.spawn("amixer -q set Master toggle")),
    Key([], "XF86AudioLowerVolume", lazy.spawn("amixer -q set Master 5%-")),
    Key([], "XF86AudioRaiseVolume", lazy.spawn("amixer -q set Master 5%+")),

since amixer is part of alsa-utils as it is said here

installing alsa-utils via:

sudo pacman -S alsa-utils

and then rebooting did the trick :).
is maybe alsa-utils not part of the qtile installation?


For completeness, I'll mark post #4 as Solution.
It is important to mark topics as "solved" for future users, when they search in the forum.
Don't hesitate to do otherwise if you prefer.
There are other aspects for the audio, but I think the most important aspect is the one above.

Yeah sure I will replace xbacklight with brightnessctl :slightly_smiling_face:


Earlier alsa-utils was dependency of pavucontrol(or dependency of its dependency) but it is no longer now.

Thanks for pointing I will make it dependency of qtile-setting
