It does, thanks!
I guess we just need to wait for the protocol to be merged and then we can tag the surface then. Until then, if I understand correctly this blog post, the best thing to do on wayland with color management enabled is to set the display profile at the application level (for apps that allows to do that, which include GIMP, Krita, geeqie, darktable, RawTherapee) to rec.709 with a pure 2.2 gamma to get reasonable colors
Hello everyone,
Just for your informationâŠ
As regards the color management for softwares based on QT (Krita, Scribus, QCAD, FreeCAD, QGIS etc etc) there is this interesting news:
To sum up:
âUpstream, the QGIS team is currently working with Qt developers to improve Qt to support CMYK in their color models and conversion, focusing on PDF and TIFF formatsâ
I am experimenting with Hyprland and apparently I am finding out that it is actually possible to live in Wayland if you have a wide gamut screen. darktable seems to work fine with Xwayland and is color managed (just put the screen profile to .config/darktable/color/out), and it is also possible to set the screen profile inside Firefox which is a Wayland native. So for now the best thing to do is actually disabling system wide Wayland color management. But I have to do further tests with Digikam etc. So the only thing that is really still missing in Wayland is calibration/profiling software.
Thanks for the hint, I was going through xiccd
but since I only need profiles for Darktable this should be much easier.
both digiKam and RawTherapee are actually Wayland native
Geeqie does not start on Arco Linux Hyprland live (canât install Flatpak) but XnView is Wayland native and color managed (monitor profile can be set inside the program)
You know what I truly donât understand and it really boggles my mind?
Where are the people from all the huge companies releasing graphics software for Linux? Why arenât they engaging in the discussion? They are, after all, making huge amounts of money from it and they would make even more. I think itâs probably worth mentioning them here and maybe us âbanding togetherâ might be worth to bring this issue to the attention of the big software companies that actually stand to directly profit from that work.
Just some of the huge âindustryâ software that works on Linux and required proper color management:
BlackMagic DaVinci Resolve also Fusion
Adobe Substance 3D
Autodesk Maya
Maxon (various software like Cinema 4D etc.)
SideFX Houdini
Foundry (various software like Nuke)
Otoy Render Engine (âThe worldâs first spectrally correct, unbiased render engineââŠ)
RodeoFX OpenWalter
ftrack
BorisFX
Weta Digital
And about Weta Digital, here is a quote from Dustin Kirkland:
Next I attended Paul Gunnâs talk in the SysAdmin Track on Weta Digitalâs effects rendering data center, here in Wellington. Very early in the talk, he noted that 90% of their artists run the Ubuntu Desktop, with the remaining 10% using Windows. Adobe Photoshop is one of the few remaining apps that still need Windows for. He went on to talk more about their server render farm, noting that all of their 35,000 cores are also running Ubuntu. In the talk, he called these âUbuntu Serversâ, which to me meant that they were installed from the Ubuntu Server seed.
Also, I remember one guy telling me how they only use Linux to produce Dr. Who, after a bit of digging, Iâve found out that Linux has been used at BBC by content producers since 1999!!
There are also âLinuxâ foundations that are apparently involved with VFX industry etc. How come none of their people are involved in the discussion?

What Iâm wondering is when will everyone stop pretending like Linux is not used in the graphics industries? Itâs literally everywhere, the only proprietary software that comes to Linux is precisely that kind and yet the OS itself gets the least love in that area.
Wayland has an opportunity to make something right here. Atm the best color management is on MacOS so it would need to be at least on par with that.
Maybe we need to do some outreach to those proprietary software vendors for something to actually be done? This is a bipartisan issue, both foss and closed after all xD
You also said you wanted a concrete things you could share with devs. I just want to reintroduce this into the thread in case some ppl have missed it and since the link to the original seems to be broken:
https://web.archive.org/web/20211028152104/https://www.argyllcms.com/CM_requirements.txt
The current standard is RHEL (or clone) where X11 is at least supported until 2032 (longer if you pay extra).
Future features - Confidence in the distribution provider addressing VFX-specific
needs such as Wayland support for complex DCC tools, and support for
specialized hardware such as professional HDR, wide gamut and XR displays.
So, itâs up to the distro (RHEL) to fix the issues before X11 is EOL.
in defense of my colleagues in the vfx industry, they 1) are engaged quite a bit in the aswf and 2) are very busy people indeed. i donât see people working under such deadlines and with these workloads (getting renderers/compositor nodes/texture drawing programs right, pushing shots out the door) also fixing the base system unless it is broken.
May I note that under x11 the CM is also not in a perfect shape. Here I shortly described my exercises attempting to get 10-bit from X11 pipeline. Lost in vainâŠ
âŠwhich in turn may suggest that we wonât get a proper CM until 2032âŠ
Iâll still take ânot perfectâ (but still works, x11) vs not working or complete Wayland
can you prove that the gnome wayland colormgmt stuff, which they have for quite a while already, doesnt work?
Loading an ICC profile isnât color management; its half of whatâs needed.
Running displaycal in a native Wayland window, completing the profiling and loading the resulting ICC profile is what is needed. The protocol has barely been written and not even sure its merged, so how could it work?
Add the issue of apps (like gimp, krita, inkscape, blender) not supporting wayland way of doing colour management yet, which is not just one way but two or three way depending on which desktop environment you run the app. And I do not think apps (which are now running under xwayland, which is probably stuck in sRGB space) have working colour management under wayland yet.
Yes, theyâre working on it.
But it isnât implemented and its not done.
you are assuming that i am talking about the new color management protocol. I am not. gnome had a workaround in place for years. i am talking about that one.
This is for gaming and HDR not about graphic design photography and creative apps. I know you think it is possible right now but it is not. None of the apps that we care support native wayland colour management right now.
Again we really really want to use it we want to ditch X11 so bad but sadly it is not possible right now.
Itâs work thatâs being done in areas that end up sharing the same problems that need solving. He didnât say anything was ready at the moment, merely that work is being made, so thatâs a rather strange reply.
That said, HDR is as relevant for âcreative appsâ, than anything else weâve been talking about here.
The focus is more in the gaming side from what I see. Yes we are very fortunate HDR shares things with colour management.
