Your distro has nothing to do with it. As long as you have grim, slurp and wl-copy installed and are on wayland you can do: grim -g "$(slurp)" - | wl-copy to copy a selection. You can also do grim - | wl-copy to copy the entire screen.

At the moment my darktable-pc uses Xubuntu with XFCE 4.18.1 with X11. I did a lot of changes with the standard-settings and it is for 90% ok for me, but sometimes is horrible, especially some websites I need. For instance sliders in geequie donât work correctly, while it is ok with Kubuntu. So I want to switch to wayland with the next install in 2026 (Kubuntu 26.04) or maybe earlier. My test pc with Kubuntu 25.10 has some problems, eg with window rules, but this can be accepted. What is unacceptable, if darktable doesnât work.
So I need and want wayland ASAP.
I am waiting until dt 5.4 is available from Opensuse Build Service. Looks like it is down at the moment.
~# apt-cache policy darktable

I try to explain it in a few words.
I need fast screenshots, without being asked for a filename. I want to press a shortcut and that is all. I have to be ready for the next screenshot.
The filesize should be as small as possible. I am playing at the moment with different values.
I want the active window too. This can be a big challenge with wayland.
Here is an example as part of my script:
spectacle -fbn -o >(Convert - "$screenshot_file")
Note Convert is not the command convert.
Convert () {
local source=$1 dest=$2
convert "$source" -resize 70% -quality 20 "$dest"
}
I didnât find a way to do this with Gnome, because spectacle doesnât work with gnome.
And that is the problem:
# apt install wl-copy
Fehler: Paket wl-copy kann nicht gefunden werden.
Translated: wl-copy cannot be found, using Kubuntu 25.10

This is a well known error message.

This thread is so confusing. Wayland has nothing to do with opencl.

Thanks for clarifying this. So if you use wayland with dt before 5.4 and there are problems, it is not opencl related? The speed advantage of opencl with rendering should work in anycase with wayland?
Thanks to all for helping for my off-topic-problem.
What a problem are you trying to solve?
dt uses OpenCL to do basically math. OpenCL is not used for display rendering.
At the moment I use Xubuntu 24.04.3 LTS (no wayland) with darktable 5.2.1-1.1+92.1 and I donât notice problems. For other reasons I would like to switch to wayland, but not if I get problems then with darktable. A good working darktable is a killer argument.
It looks like it is a good idea to wait for dt 5.4 or later, which is published very soon. I donât want to change to another distro (from XFCE to Plasma) if I solve some problems and get other problems. The discussion here is about darktable. Other things I have tested and the problems are more or less ok.
What is the next version after 5.4 and when is it published?
Ive been using Wayland for a while on Fedora KDE, no issues. Compositor issues with Wayland were resolved in dt master. darktable 5.4 should be out in 2-3 days (released in GitHub). You will then need to wait for the packagers to update it in your distro of choice.
When people say Wayland issues, it is normally not a Wayland issue. It is a compositor using Wayland. You need to figure out what compositor Xubuntu is using.
I donât know about other distros, but under OpenSUSe I can decide at login time whether to use wayland or XOrg. So no need to reinstall anything to test it (of course, backups are always a good idea when testing this kind of thing, if only to keep configs intactâŚ)
Iirc, there were color managment issues with Wayland, which is why darktable did not want to support it (officially). I have no idea what the situation now is.
What I did see in one of your original posts was a reference to flatpak. That is known to cause some issues with openCL, but, as said by others, those have nothing to do with wayland.
Should be 5.6, and in about 6 months, if they maintain the schedule used in the past few years.
Just for information, Is that Wayland native or XWayland?
gnomeâs builtin screenshot tool does all of this out of the box for me.
I just get a new ~/Pictures/Screenshots/Screenshot From 2025-12-09 03-49-56.png . and the popup from the screenshot keybind has the option to take a screenshot of a window/full screen/section of screen.
