Red Hat Is Hiring So Linux Can Finally Have Good HDR Display Support

[dec05eba]

BTW, this HDR feature will be wayland exclusive. More info from Christian Schallers post here

https://blogs.gnome.org/uraeus/2021/09/16/cool-happenings-in-fedora-workstation-land/

And no, despite what some people claim, X11 does not support HDR and it probably never will. I think that from this point going forward, this will be increasingly common. We will see features being added that only work with Wayland, which is natural after all. Wayland and associated technologies like pipewire for screencasting and libei for emulated inputs are closing the feature gap to X11 and once this is done we will see new capabilities and features that build upon wayland that will not be brought to X11.
It also looks increasingly likely that wlroots will be the defacto building blocks for future wayland compositors. We already have Sway, Wayfire, Valves Gamescope, KwinFT, Phosh and some others that are built on wlroots.

Im literally watching a hdr video on youtube right now with chromium + nvidia + x11 and it works and chromium even detects and says that hdr is enabled on my system

And you have a HDR capable monitor?
It seems very unlikely that ChristianSchaller ,the head of RedHat's desktop team would be wrong. Furthermore, you have karolherbst, Nouveau developer working for RedHat, telling you that you are wrong:

Now, what are the possibilities for them to be wrong and you right? I would say the chances are almost nonexistent.

You sure about that? 'Cause BB claimed just a few months ago that VW, BMW and Mercedes are using QNX

but they aren't using qnx exclusively. and btw they are using it less and less

Well, wswartzendruber did mention gaming, but that's still not something the majority of users do, on their Linux desktop.

This comment is rather puzzling, as if you're expecting that each advancement in technology should be immediately relevant to the majority of users. Traditionally, the boundaries of tech are pushed by the most demanding users. Then, as the tech matures, it trickles down to the mainstream, where other opportunistic applications take advantage of it and widen the pool of beneficiaries.

In this case, the early adopters should be:

• Video production
• Video consumption
• Photo editing
• Games

Once the tech has matured, perhaps browsers will embrace it. The arrival of newer image formats, and the fact that most phone cameras have supported HDR for a while, should mean there's no lack of HDR content to populate the web. This should provide benefits even to the masses of unwashed, bearded Linux admins.

Absolute most smartphone (cameras) output to JPEG which doesn't support HDR in any shape or form unfortunately, and people don't shoot videos in HDR because of humongous file sizes. HDR is still gimmicky as hell for most users out there even on Windows, of course rare HDR enabled games and rare movies notwithstanding.

Probably the client list of his employer, Red Hat.



Oh, glorious how you're actually trying to tell the man from Red Hat that he does not have any customers that run applications like DaVinci Resolve.

Well if you are talking about color management, as stated earlier they don't use Xorg for this but an external capture device. The fact that it runs here on Linux is irrelevant because they essentially bypassing the entire OS in this process (which isn't surprising considering that color management is a mess in Linux).

I don't get what your point here is.

All I can tell from public press is that QNX Neutrino's use is actually increasing (see https://www.heise.de/hintergrund/Kuh...h-4863254.html) in auto space because

1. Its a proper hard RT os (Linux requires a lot of patches for this and even then its not the same). Depending on what component we are talking about in a car, this is a requirement
2. Its a microkernel which means it can properly isolate components. If some driver crashes in Linux it can hard lock the entire OS, you don't want this to happen when you are in the middle of driving a car

In fact you if you look at the list at https://qnxauto.blogspot.com/2015/06...x-in-cars.html (last updated 2015) there are more car manufactures that do use QNX rather than ones that do not

Nonsense! Any professional grade NLE runs far superior on Windows or OSX than it does on Linux, if it even has a Linux port at all.

But feel free to provide any links that support your claim.

Almost every Autodesk product runs on Linux, and it is generally agreed that rendering on Nvidia hardware on Linux renders faster in Maya, the industry standard for decades for animation and creation, used in most big name movies from Monsters, Inc. to Toy Story, not to mention companies outside of Disney.

Even Blender renders faster under Linux vs Windows, and OSX is a joke, thanks to not supporting OpenGL.

And you know that Chrome/Chromium doesn't just bypass X11 for that like every software wanting to do something like that?
That HDR doesn't work with Wayland isn't because the capability hasn't been added yet, but mainly because Wayland is built to prevent all the hacky solutions from working that are used to get many things to work under X because X never supported those features itself.

[Awesomeness]

I don't get what your point here is.

"Actually almost all studios use Linux for the desktop."
–"they tend to use Linux for servers"

And after you've been proven wrong, you now don't get the point. Oh man, you're hilarious. 🍿

Even prosumer cameras and professional DSLRs shoot to JPEG as the default capture mode unless specifically instructed otherwise.
