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

[birdie]

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

You're hallucinating. Chrome under Linux doesn't support anything but 8bit output.

Here's how it's "running" at "DefaultDepth 30":

Graphics Feature Status
Canvas: Software only, hardware acceleration unavailable
Compositing: Software only. Hardware acceleration disabled
Multiple Raster Threads: Enabled
Out-of-process Rasterization: Disabled
OpenGL: Disabled
Rasterization: Software only. Hardware acceleration disabled
Skia Renderer: Enabled
Video Decode: Software only. Hardware acceleration disabled
Vulkan: Disabled
WebGL: Software only, hardware acceleration unavailable
WebGL2: Software only, hardware acceleration unavailable

"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. 🍿

"Cannot actually read properly" (or refuses to do so)
- "changes the definition of studio/workstation/desktop to suite the argument"

And after its been proven that you twist what people say and cannot comprehend finer details. Oh man your hilarious 🍿

Also, I've just verified that Firefox 92.0 doesn't support 30bit color either.

This image (30bit) looks the same in every tested mode, browser or application in Xorg/X11.

Under Windows you can see it as intended.

Neither mpv, nor ffplay can display 30bit videos either.

I can see the vertical bars for grey and green in Linux, but not the blue and red.

Does that mean anything?

You should see 256 bars for the 10bit parts of the image, and only 64 bars for the 8bit parts.

Chrome, Firefox and native image Linux viewers all show me 64 bars.

Your Chrome looks somewhat borked. This is mine:

Your Chrome looks somewhat borked. This is mine:

You seem to be running Wayland with a 24-bit color depth. I showed its output when running Xorg with a 30-bit color depth.

[Sonadow]

You should see 256 bars for the 10bit parts of the image, and only 64 bars for the 8bit parts.

Chrome, Firefox and native image Linux viewers all show me 64 bars.

Wine applications fail to start altogether

wine: Unhandled page fault on read access to FFFF0000 at address FFFF0000 (thread 0024), starting debugger...
winedbg: Internal crash at 0xffff0000

Then I guess mine should be the same as well. On Wayland.

BTW, I didn't mind Windows 7 for running office apps and stuff, but when my employer finally upgraded us to Windows 10, I was thoroughly unimpressed. Since I don't run it at home, I can't say whether most of the issues were the core OS or just how they deployed it, but it was the slowest and most unstable Windows I ever experienced since probably Windows 3.1. Granted, I skipped Win 98, ME, Vista, and 8. And I never upgraded until there were a couple Service Packs released, either. AFAICT, Microsoft hardly gives a shit about Windows, anymore. I think they mainly just see it as a way to rope in customers for their cloud services.

I would strongly disagree. At my last job we all used Win 7 and eventually it was announced that all systems would be migrating to Win 10 and we all bitched non stop. When Win 10 first came out, on multiple forums I moaned and groaned and complained and openly argued about the supposed telemetry, I went on and on about how Win 7 was better and initially I really believed it was.

But I have to admit, after my job forced us to upgrade, I came to realize what a great OS Win 10 is and I was remined of how I felt about replacing Win 2k with XP64 and replacing XP64 with Win7.

My mother and brother also threw a fit when I told them I wanted to upgrade their systems from XP to Win 7 and from Win 7 to Win 10. They now love Win 10.

For me, the most impressive thing about Win 10 is its stability and more importantly how resilient it is to attack, its built in ransomware protection is very good and reminds me sort of SELinux; I have tested Win 10's ransomware protection extensively and it works as advertised, maybe better because it also stops non ransomware viruses.

Almost every Autodesk product runs on Linux.

I don't know what's sadder, that you can't be bothered to even go to Autodesk's website to see that you are wrong or that the two people that upvoted you also couldn't be bothered to check their site:

Please notice the filter list on the left, under OS type, they only list Windows and Mac, no Linux.

That's a swing and a miss for you.

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

And the day I decide to built a Blender render farm in my basement that will come in very handy.
