There is a plan to add DDC to the Linux kernel, so that any desktop can manage external monitors using the same APIs they use to manage internal laptop panels. Hopefully that would mitigate the problems you mention.

https://gitlab.com/ddcci-driver-linux/ddcci-driver-linux

Using this driver, Powerdevil does not allow you to set values individually per monitor, instead gives you only a single slider. This is absolutely sufficient for single monitor or multi monitor setups with identical models, but in my case I need the option to set it individually since my monitors are all differently bright on 100%.

I 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!

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. https://github.com/waydabber/BetterDisplay

Can I just say... such a healthy way to help the ecosystem but retain distinguishing features

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…

> Therefore I don't get your outrage on people promoting this other app. You are free to keep using gddccontrol, the existence of other similar apps doesn't mean gddccontrol will stop working for you.

Just a note — “outrage” describes a state of extreme agitation, it is probably not accurate to use it to describe the post you’ve responded to.

There is also Clight ( https://github.com/FedeDP/Clight ) if you want automatic backlight adjusting given ambient brightness. It supports external monitors through ddcutil C library and has many more features to offer. Disclaimer: i am its creator ;)

It is Linux only btw.

random question for you: i have a sony oled display that auto-dims on low color change activity (this is impossible to disable - believe me, i've tried, even in the diagnostics menu). do you have any idea how this could possibly be circumvented?

Thanks!

That is an ABL or Automatic Brightness Limiter and it’s one of the things that’s messing Lunar’s brightness Sync algorithm because the max brightness is constantly changing.

It might be possible to disable from the monitor hidden service menu, if you can find a way to enter it. But it will also greatly decrease the lifespan of the diodes as OLEDs are not made to go so long with high brightness and heat.

If the monitor does not provide such an option, there is no way to circumvent this as the function is embedded in the monitor firmware.

I've tried setting up clight on various occasions and now gave it a shot again, whilst I appreciate all the documentation I'm still struggling to get it working on NixOS with swaywm on a laptop. I'm primarily interested in adjusting screen brightness based on my webcam. I'm already using redshift/gammastep.

Automatic detection of default and supported resolutions and information about DPI? Or is it not the same?

DDC is how monitors send EDID information about their capabilities to the computer. DDC/CI adds the ability for the computer to send commands to the monitor for things like brightness and color settings and input selection. So Windows obviously is using plain DDC to offer you the right set of resolution choices, but none of the DDC/CI functionality appears to be exposed to end users, making it effectively unsupported…

I thought it was supported by NVidia control panel since ages?

P.S. Not a user of NVidia now, might be a fake memory.
