No Longer able to Change Brightness on Laptop w/ Keybinds

[zangoku]

I have a lenovo thinkpad x13 gen 3 with i3wm and the brightness would change when pressing the brightness keys on the keyboard which are F5 and F6. When I press those my mouse turns into an infinite loading when not hovering on a window so like on the background. I installed brightnessctl and it lets me change the brightness when setting the brightness via the command line like brightnessctl set 100. It used to work before. All other F keys work except F4 which is the mic mute button which may or may not have worked before, I don’t use it much.

What desktop environment is in use?

[zangoku]

i3wm as stated.

You will have to find the binding in your config (looks like bindsym XF86MonBrightnessUp exec brightnessctl -c backlight set +5% or similar) and update it to whatever configuration works for your machine.

I’m not sure why, but this seems to be an ongoing thing for i3. There are quite a few topics in the forum with this same issue; see for yourself:

Issues with brightness control on i3wm ( in built keys shortcuts )

Try this: bindsym XF86MonBrightnessUp exec brightnessctl -c backlight set +5% bindsym XF86MonBrightnessDown exec brightnessctl -c backlight set 5%- Brightnessctl is in extra. Other options are light & xorg-xbacklight which off course have their own syntax. The problem with these keys is they are hardwired in the bios, so you might not get anything to work.

Change brightness

Hello, I want to be able to use XF86MonBrightnessUp and XF86MonBrightnessDown to adjust brightness levels on my laptop. System Information: Kernel: 6.5.4-arch2-1 Device: HP Pavilion Aero Laptop 13 GPU: AMD ATI Radeon Vega Series OS: EndeavourOS Linux x86_64 Window Manager: i3wm Here is what I have tried so far: According to arch wiki, xbacklight only works with intel GPU, and running it manually gives me No outputs have backlight property. bindsym XF86MonBrightnessUp exec xbacklight +10 && …

Issue with changing of brightness of screen with Function keys

[ I am using i3wm] I earlier had the common problem as most have here. Function keys did not work for changing brightness. But i worked on the issue. and fixed it. What i did there was exactly as stated here: https://forum.endeavouros.com/t/laptop-brightness-keys-f3-f4-doesnt-work/44866/11 But here is another issue with that. I have set brightness to change in steps of 5%. But when i use function keys to change it. The change is random. like: For the first key press. the brightness decrea…

Laptop brightness keys(f3&f4) doesnt work

Change the xbacklight -inc $brightness_step -time 5 in the case statement to brightnessctl -c backlight set +5%. Change the xbacklight -dec $brightness_step -time 5 in the case statement to brightnessctl -c backlight set 5%-.

Brightness won't change

brightnessctl is a utility that can be used to control screen brightness in Linux, and it can be used with i3 window manager. To use brightnessctl with i3, you’ll first need to install the brightnessctl package from your Linux distribution’s package manager. Once you have brightnessctl installed, you can use it to set the screen brightness in i3 by binding it to a keyboard shortcut. For example, you can add the following lines to your i3 configuration file (~/.config/i3/config) to bind the XF86…

Some i3 notebook users?

For me the default didn’t work out of the box with Dell Precision. Now AFK, will elaborate later LATER: Apparently I have also switched to brightnessctl suggested by ishaanbhimwal, which works perfectly.

Keyboard inoperable after I messed with 10-amdgpu.conf

For brightness control, there is a lightweight tool called brightnessctl, which is available in the community repo. If you are using i3wm, you simply have to add two keybindings that call brightnessctl. For example: bindsym XF86MonBrightnessUp exec --no-startup-id brightnessctl -q set +5% bindsym XF86MonBrightnessDown exec --no-startup-id brightnessctl -q 5%- I wasn’t aware you have to mess around with X Server configuration files to enable backlight…

Brightness control keys not working on my i3WM install

Indeed, it did! Awesome, thank you so much! I needed to install brightnessctl and add those lines to ~/.config/i3/config. I chose 1% as I like to have a more fine grained tuning. PS- I’ll change the title of the topic and mark it solved. I will create other threads for my other questions/issues.

Xbacklight isn't working - i3 edition

I eventually found out an alternative to xbacklight that works for me. It’s called brightnessctl You use it like this: brightnessctl s 10%- to decrease the brightness brightnessctl s 10%+ to increase the brightness

It seems different things work for different people; you’ll have to do some testing and figure out what works in your specific setup.

I have the same problem with the same hardware

It was working for a while but it looks like something broken it in the last time.

The i3 config from endeavouros uses (as default) a own script “volume_brightness.sh”

When I execute the command I receive following error:

> $ xbacklight -inc 2.5 -time 0                                                                                                                               
No outputs have backlight property

So far I could not fix it but honestly I did not really invested much time till now.

instead of xbacklight I am using brightnessctl after reading:

You should simply not use xbacklight but any of the other alternatives that are more intelligent in what they do. xbacklight explicitly relies on a functionality of xf86-video-intel that isn’t replicated in any other driver, but there’s no technical reason for this dependency to exist. acpilight provides ab xbacklight drop in binary while being able to directly adjust the relevant backlight control file regardless of the xorg driver in use.

from: https://bbs.archlinux.org/viewtopic.php?id=266383

So I changed in the script ~/.config/i3/scripts/volume_brightness.sh
the following lines:

function get_brightness {
    brightnessctl | grep -Po '[0-9]{1,3}'| sed -n '3p' 
}

    brightness_up)
    # Increases brightness and displays the notification
    brightnessctl set "10%+"
    show_brightness_notif
    ;;

    brightness_down)
    # Decreases brightness and displays the notification
    brightnessctl set "10%-"
    show_brightness_notif
    ;;

now it works again like before.
Should work for you @zangoku as well after you installed brightnessctl.
