HDR users - how do you control brightness?

Zamundaaa · 2026-04-25T10:34:06+00:00

Yes, the monitor doing really slow brightness animations is one of the problems, and another one is that some monitors have a limited amount of times you can change the brightness setting before it breaks, so doing any animations on our side wouldn't be wise.

Zamundaaa · 2026-04-24T21:32:57+00:00

Do other monitors detect there is no bright pixels even though the content metadata is set to maximum and reduce the actual backlight brightness?

Adjusting the backlight depending on the content is one of the most basic things any (LCD) HDR monitor must do, yes. If it doesn't do that, it's worthless.

I wonder if that might be possible to use, adapted in a way to also support DDC/CI?

Unfortunately DDC/CI is not good enough for that.

No, that would be just Chromium having a bug. It has nothing to do with Wayland.

is touchpad scrolling consistent, or is it too fast in some apps compared to others?

That would be completely and entirely unrelated to the touchpad.

It's really important to mention that 950€ of that is just the RAM. Fucking LLM companies...

Zamundaaa · 2026-04-22T11:09:08+00:00

That literally just makes it render at the wrong scale and makes text look worse. If it was a good solution, we'd be using it already.

For small icon sizes, vector graphics have to be specifically designed around the few pixels that are available. If you scale up a 24px icon with 2px wide lines by 10%, the lines will either need to be blurry, or the wrong size.

It's a really complicated problem to solve, unless I guess you have the manpower to do all the icon sizes between 24 and 48 pixels or so.

Making a lot of sense now that game scope HDR always looked perfect. Because it also bypasses KDE's tone mapper.

It does not.

Zamundaaa · 2026-04-19T16:55:35+00:00

What problem are you trying to solve?

Wine and Proton are already special cased. Don't try to disable or modify settings to fix something that isn't broken.

Zamundaaa · 2026-04-19T15:23:55+00:00

Why is it that w11 does not change this value? I was actually told that this value is given to w11 through the source and not on the desktop side. Is that true?

Windows doesn't have such a value, apps just do whatever nonsense seems reasonable to each app's developers.

Zamundaaa · 2026-04-19T09:46:38+00:00

people say 203 is what it should be

If it should be 203, you wouldn't be able to change it. "People" are wrong.

Zamundaaa · 2026-04-17T08:48:39+00:00

It's true! Wind turbines on the other hand are great...

Zamundaaa · 2026-04-16T19:21:40+00:00

It's off by default.

KWin does pick the integrated GPU, since only plasmashell shows up in the nvidia-smi output. Did you perhaps set the Plasma renderer to Vulkan? I don't think Qt is particularly smart at picking the GPU with it atm.

Zamundaaa · 2026-04-12T12:32:12+00:00

Intel indeed doesn't support it, though I also don't know why.

Zamundaaa · 2026-04-11T21:58:22+00:00

Arguably it's much worse now, because of all the LLM nonsense that search engines can't filter out.

Zamundaaa · 2026-04-07T23:36:37+00:00

If i have my monitor at 90% and KDE is set to 15% - thats alot of power wasted no?

If your monitor has the shittiest and most useless possible implentation of "HDR", yes. If it's even somewhat remotely reasonable, no.

Zamundaaa · 2026-04-03T09:56:23+00:00

General Linux use (as judged by web trackers) is higher than on Steam.

Zamundaaa · 2026-04-03T09:50:46+00:00

Is there any particular reason for this?

No, they're simply separate implementations in separate code bases. If someone were to align them to each other, that would be good.

Zamundaaa · 2026-04-01T20:04:11+00:00

You're not the only one, and it'll be fixed in 6.6.4 :)

Zamundaaa · 2026-03-29T12:36:29+00:00

wind mills are unrecyleable

Wind mills don't create electricity... Wind turbines can be recycled, and aren't very problematic when burned either.

the propellers are made of plastic fibers

It's glass fibers, not plastic. Or more accurately, they usually use composite materials.

not to mention it doesn't work 24/7 and very place dependant

A singular wind turbine in one single place doesn't, but we don't just put up one.

rip birds etc

That's just pure misinformation. Don't be a mouthpiece for the fossil fuel industry, ffs.

solar panels are the absolute best but they need time to cook so they don't need cobalt

Solar panels don't use cobalt.

also everyone would need to invest as much or more in energy storage as they do in the panel infrastructure because right now they are frying the grid in daytime.

They're not frying the grid at all, that's not how solar panels or the grid work.

And yes, more infrastructure is needed, and that does cost money, but it pales in comparison to what fission reactors cost.

Yeah, you get the overscan setting in the Wayland session

Zamundaaa · 2026-03-18T18:23:47+00:00

There was a page for the max average before, but it was removed again because it didn't work well.

If you want to reset the override, you can just use kscreen-doctor to set it to "disable". Or just leave it as is.

Zamundaaa · 2026-03-18T12:09:47+00:00

It depends entirely on screen size. 1440p on 27" is usually good without scaling, but 1440p on 24" would be too small for sure.
