Plasma update 5.21.5 to 5.22.3 removes brightness slider from battery widget

Support KDE Plasma
, ,
1

Hi,
Yesterday I updated kde plasma from 5.21.5 to 5.22.3. I was using the brightness slider of the “battery and brightness” widget all the time to control my three external monitors brightness. Since the update the slider is gone, does anyone have an idea why?

I cannot reproduce: the brightness slider is available on my system.

Did you try any of the configuration related troubleshooting ?

3

Not OP, but I have the same problem. All I can say for now is that

rm ~/.config/Trolltech.conf
kbuildsycoca5 --noincremental

followed by

kquitapp5 plasmashell && sleep 10 && kstart5 plasmashell

did not help.

4

I’m having the same issue

modprobe i2c-dev

did not resolve it either

5

I can’t reproduce this either, but I haven’t upgraded directly from 5.21.5 - I had switched to testing some weeks ago due to another issue and therefore went all the way from 5.22.1. Wonder if it’s in some way tied to upgrade path?

6

I tried resetting the userconfig and clearing and rebuilding the cache. I deleted the cache for all applications, too.
Nothing changed regarding the slider

7

I have noticed, that the keyboard shortcuts for changing the brightness don’t work either. They worked before the upgrade. Therefore I am assuming this is a problem of some service or lib and not plasmas fault, they probably just hide the slider because the service or lib isn’t working anymore.

8

Using ddcutil i can set the brightness. So I don’t know what plasma is using for controlling the brightness

I think it uses Powerdevil, wich i think utilizes ddcutil

11

what about finger print unlock feature when be added?

12

I updated directly from 5.21.5 and still have the brightness slider. I can only say that I use (almost) the default KDE settings that came with Manjaro.

13

I had the same problem, I was using the slider to control the brightness level on external monitors.

The issue seems to come from the upstream Arch package for Powerdevil, removing support for the ddcutil, as one can see here: Disable ddcutil support, it's buggy and unmaintained (FS#70525) · archlinux/svntogit-packages@274840f · GitHub

So it turns out in Manjaro too we’re now getting Powerdevil packaged without support for external monitor brightness.

I solved the issue by temporarily pinning my version to 5.22.2.1-1.

Thanks.
I used “downgrade” Downgrading packages - Manjaro to revert to 5.21.5 for now, I do have a working slider again.
That’s obviously not a longterm solution, because it could break something when upgrading again while leaving powerdevil at a old version. I will mark this as solution for now, but hoping there will be proper support for external monitors again soon.

@BoBjoni123,
although I’m not sure what you meant with

slider of the “battery and brightness”

I guess, that I’m facing a similar issue, which I described here. In addition to the brightness problem, I figured that the LED in F4 indicating the microphone muting is not working here. Is your’s OK?

On the other hand I’m wondering, that there is not much “noise” in the internet about this issue. How to address this to KDE-guys in order to have a solution soon?

16

As i pointed out in my original post, I am using the “battery and brightness widget” that kde provides to change my screens brightness.

I don’t think you are facing the same issue:
I am controlling my 3 external Monitors brightness, I am not using a Laptop.
Since afaik most laptops screens are controlled by ACPI, whereas external Monitors are controlled via DDC/CI through ddcutil.
The issue in this thread was that an update of powerdevil which kde uses, removed ddcutil support.
If that would be your Problem, you shouldn’t be able to even see a brightness overlay when pressing the keys to change the brightness and you shouldn’t be able to see a brightness slider on the widget.

The microphone thing is a entirely different topic that doesn’t belong in this thread. I can’t help you with that because I don’t have the Knowledge.

Well there’s probably not much “noise” because many people seem to not have that problem.
