Curious from people who follow its development closely.
- What protocol are about to be finally implemented?
- Which ones are still a struggle?
- How many serious protocols are there missing?

From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Been working great for me for ~1 year on my desktop and closer to 2-3 on my laptop.
The only thing missing for me was Barrier for input sharing, which libei is supposed to fix. I ended up going for a hardware solution as Barrier is jank af anyway.
Only thing not working for me is HDR (should be fixed in Plasma 6.1), not like you could do HDR on Xorg anyway. Also no HDMI 2.1 but that's because fuck the HDMI Forum.
Performance-wise, just blows away Xorg in every metric, and explicit sync should make that even better.
Oh so a Plasma update broke HDR. I was wondering what happened when HDR went from looking primo to looking washed out and ugly. I'll just wait patiently on SDR. :)
Were you using patched KWin or something? Because experimental HDR support is supposed to be one of the big features for 6.0, so unless it broke in 6.0.3 or something, you shouldn't have had an update to break HDR in the first place because it wasn't supported.
No just whatever came from the Arch repo. I'm not entirely sure what version I'm on right now, but it's been broken for me for maybe 2-3 weeks. It's not the biggest deal and I'm used to unimportant features like that occasionally breaking.
Well that's a weird one then. It got released February 38th and took a couple days for Arch to get it. I had the washed out colors too but I didn't have any HDR before that. That's ~6 weeks ago so yeah it's probably 6.0.3, the last that came out about that 2-3 weeks ago. I guess you were one of the lucky ones it worked and then broke! With a bit of luck it'll be fixed for good on 6.1.
Any chance it's hardware dependent? First I'm hearing of this and I just toggled it off and on to be sure I wasn't seeing things - mine is definitely working. I'm all-Intel FWIW.
It works for most people but there's some issues with some monitors where the color saturation doesn't work well and result in washed out colors compared to SDR.
It will also output RGB into YUV buffers if you have a display that only supports YUV colorspaces, so you end up with a very green and reddish purpleish screen.
Initial HDR support was introduced in 6.0, and 6.1 is supposed to bring some fixes for the washed up colors. I haven't found a bug for the YUV stuff and didn't have time to do a proper bug report.
Ah makes sense, thanks for the additional info!
Could be that the graphics card is outputting an HDR signal (Rec. 2020 color space), but the monitor is in SDR mode. That would result in desaturated colors.
I wish it were that simple, but no. The monitor enables HDR automatically when being fed an HDR signal. I can confirm that HDR is enabled on both ends and it still ends up washed out, whereas before it was perfectly fine. :(
What hardware solution did you go with?
A bigger desk so I can just roll the chair a few inches to switch to the work laptop.
My original plan was a keyboard/mouse only KVM, probably a Teensy or a RPi or something of the sorts. But I got lazy as the extra desk space has just made it a non-issue for me. I also have a Logitech mouse that can switch between devices, so if I was going to really need that setup I'd probably just get the matching keyboard.
What's supposed to not work, and what am I supposed to have fixed in 6.1? There haven't been any major changes to HDR since 6.0
