Wayland color management

Just tested Hyprland-git, it actually can show colors outside of sRGB while color management is enabled, too. The stable version can’t.

Always the HDR, never the profiling… But perhaps there’s something beyond the headlines.

You just have to scroll up further in this thread:

As I understand it, this is about doing things in hardware instead of software, so it’s faster. And I’m not sure it’s intrinsically bound to Wayland either.

Ok I think I just discovered one of the important „flaws“ of wayland: davinci resolve is not wayland native.

Seems more like a flaw of davinci resolve :wink:

Yes, I mean its typical of closed source software, the devs are sleeping.

But you know how important the Software is?

Of course. I guess Davinci/Blackmagic must have some data on their linux userbase and will act accordingly. Don’t studios use LTS releases of stuff like RHEL and rarely update? I doubt they are worried about individual users

The officially supported distro is rocky linux 9, which is based on rhel. But current version of rocky is 10, which is not supported because there is no x11 session any more.
Davinci resolve runs best on linux with nvidia. Macs dont have nvidia graphics.

The entertainment industry/davinci resolve is the main reason why there is even an nvidia driver for linux.

Wayland color management support is so new and so sparsely supported that I suspect we won’t see Blackmagic move Resolve to Wayland until things settle down a bit.

(As a side note to those that are unaware, Blackmagic actually sells hardware for the explicit purpose of bypassing all OS color management and giving Resolve full control over EXACTLY what goes out of the SDI or HDMI port, including during blanking intervals.)

I think dat the whole AI thing is the reason… All those clusters are running NVIDIA hardware… Much much bigger then the few studio’s that what to run davinci resolve on linux…

We need to take historical facts into account. NVIDIA has had a Linux driver for a decade, probably two by now, even before AMD(ATI) supported Linux or open sourced their driver. Scientific computing and of course what Anna said really is the reason the driver has existed for so long.

At least two. Pretty sure I was running linux hwaccel with nvidia in 2002-2003ish.

At this point a decade ago is post-AI by a decent margin - Krizhevsky’s breakthrough paper was 2012

I’m about to run Linux again, after a multi year hiatus.

What do I need to do to run Darktable for the DP3 color space these days? Is the technology ready? Do I need specific distros or configs? I have hardware calibrated screens, so no profiling is needed.

No specific configuration is required with the latest Darktable. I’m on GNOME and darktable runs natively on Wayland and it can read the display color profile from colord.

From the 5.4.0 release notes

Many GNU/Linux distributions have dropped support for X11 leaving only Wayland. Darktable has received many fixes to work properly on Wayland including display ICC profiles. This version 5.4 should work on Wayland as good as it was on X11.

How do you create the color profile on Gnome Wayland (mutter)?

I booted a Fedora XFCE spin live CD which is still on X11 and used argyllcms to create the profile and calibration curve. I think in theory if you don’t need calibration than it’s possible to create a profile directly within wayland.

How do you know that the profile created in x11 will work on Wayland? Wayland has different brightness controls.

I don’t understand your comment around a profile without calibration.

I use hardware-calibrated displays. You feed raw DP3 to them, and they do the profiling and adaptation internally. As such, I just set my OS to the DP3 color space, but have no need for an ICC-based lookup table.
