If you use gnome, this extension has worked well for me.

Re: KDE Plasma Widget for external monitor brightness adjustment
#22If your distro doesn't have a package for the backend of this plasmoid yet, it invokes the backend with[1]:
python3 -m ddcci_plasmoid_backend
git clone https://github.com/davidhi7/ddcci-plasmoid \
&& cd $(python3 -c "import site; print(site.getsitepackages()[0])") \
&& ln -s $(cd -)/ddcci-plasmoid/backend/ddcci_plasmoid_backend .

gddccontrol has been around for ages on Linux and it's not exclusive to a single desktop environment (and I'm sure there's a plethora of alternatives, but that's just the one I use).
>gddccontrol has been around for ages on Linux Linux has many such apps, but many are just CLI based, or buggy/janky GUIs, or just don't work at all, depending on what HW/OS you run. Having a great looking app the integrates seamlessly into your DE and justworks(TM)(hopefully) is big step in the linux world. >but gddccontrol has a GUI, has been supported since 2004 and works fine in 2023 @Garcia98 gddccontrol GUI mig…
Sure, but gddccontrol has a GUI, has been supported since 2004 and works fine in 2023, that's why I find it a bit odd that he didn't know what to recommend to Linux users until now.

I knew about gddccontrol, it's just not what people were looking for when they were asking me about an alternative to Lunar. I obviously gave them any alternative I could find, but all the responses I got were that a simpler easily reachable UI and keyboard shortcuts for changing brightness were what they expected.

#26I develop Lunar ( https://lunar.fyi/ ) for controlling monitors on Mac and stumbled upon this gem for Linux which I wanted to share with you. I regularly get asked to recommend something similar to Lunar for Linux and Windows and while there's TwinkleTray for Windows, I didn't have a good recommendation for Linux. Glad this finally exists! A lot of people also use MonitorControl for Mac and might be curious what's th…
I've user Lunar for quite a while, then moved to MonitorControl, and am now on BetterDisplay, which notably includes DDC/CI over the M1 HDMI ports.
Also its ability to fake screens of arbitrary resolutions e.g for headless machines is solid gold.

#27This is cool, thanks for sharing.
I use a bash script to adjust brightness and contrast from the command line.
I invoke it as `brco 80` etc where 80 sets it to 80%. The script is:
$ cat `which brco`
#!/usr/bin/env bash
set -euo pipefail
# use `ddccontrol -p` (probe) to find the following:
mydevice="i2c-7"
# brightness
ddccontrol -r 0x10 -w $1 dev:/dev/$mydevice &> /dev/null
# contrast
ddccontrol -r 0x12 -w $1 dev:/dev/$mydevice &> /dev/nullRe: KDE Plasma Widget for external monitor brightness adjustment

Yes, BetterDisplay got DDC support on HDMI M1 soon after its dev learned that I added it in Lunar: https://github.com/waydabber/BetterDisplay/issues/1361
I’m friends with Istvan (the BetterDisplay dev) from the time he was a Lunar user, and we usually share implementation details for non-Pro features.

Maybe because it's discoverability is bad. I've been looking for something to control screen brightness because I wanted to give Linux another shot, so this random post was a lucky find.
If I look for this topic on ddg I either find a Ubuntu wiki entry(not really relevant to me on suse with KDE), the arch Wiki which focuses solely on technical details and clis. The first ten articles are clis, a lot of them truly strange ones like writing magic numbers into random system files.
Not a single mention of gddc tho, and the manpage is not a very good advertisement either...

#30This is amazing! Thank you for sharing, can confirm it works perfectly on Fedora + KDE + (2) Dell U3415W.
