tried copying default starter config and running got:

I suspect it could be because of the libcyaml "hack" you had to do to get it compiled in the first place. You mentioned in the previous issue that you had to copy the headers for libcyaml. I myself had built from the git source and it had worked ever since for me. Just maybe, removing the libcyaml-dev package and just using the git version might help here?

[karlstav]

build cyaml from source, that seemed to helk. for some reason I ahd to add:

LD_LIBRARY_PATH=/usr/local/lib

to my environment.

however, now I get:

Error: Shader 'linear' not found.

do the shaders need to be copied somewhere?

[Roonil]

I see. That's actually helpful, I'll add a section on the Wiki if something like this keeps cropping up. As for the shaders, the contents of the "shaders" directory need to go into ~/.config/WayVes/, so you should have the following directories (I have this mentioned in the usage section and also the commands are available there):

~/.config/WayVes/linear
~/.config/WayVes/angular
~/.config/WayVes/ncs
~/.config/WayVes/chain
~/.config/WayVes/utils

The relevant .glsl configuration files, the yaml file and the styles.css file go into ~/.config/WayVes, so at the root of the directory

[karlstav]

yea it works now, but as mentioned nothing really happens

[Roonil]

Do you not get any visuals? Gnome's Wayland implementation does not support the Layer Shell Protocol so it "should" be because of that

[karlstav]

no visuals no

[Roonil]

Since GTK4 introduced the new Vulkan renderer backend, I've also had to set some environment variables (I have implemented the suggested workaround for this in my source code, however that does not seem to have any effect), the variables being GSK_RENDERER=opengl and GDK_DEBUG=gl-prefer-gl. Can you try these and let me know the gtk4 version on your system?

No visuals strongly suggest that it is because of these. I've also included a mini guide on the Wiki to let an older gtk version drive WayVes in case of performance issues (also because of vulkan and their new opengl renderer, although the performance should be good enough for non-expensive shaders), and the older versions do not need these environment variables at all. If you can, try setting these variables and run WayVes. It should open some shaders in a window, though they might not react (I saw this happen with no layer shell support while testing on my system). I might also include a workaround to actually allow it to run in individual windows when layer shell is not available.

[Roonil]

I managed to get it running on Ubuntu on a VM (25.10), I've posted the details in the other issue but it indeed seems that the visuals don't get on the screen because of the missing layer shell implementation. Using the plasma environment produces the visuals correctly since it supports the layer shell protocol

[Roonil]

@karlstav the latest release includes falling back to windows when the layer shell protocol is not supported. It should work on Gnome now.

I'm having the same error on Ubuntu but my wm is niri and I do have gtk4-layer-shell installed from git. I even set the env variables listed above. Latest libcyaml, too.

Are you still getting the invalid key error? Are you using the git version of libcyaml, or did you install it using apt? Using the git version is recommended.

[vaskark]

@Roonil Thanks for responding.

Yes, I am using libcyaml, latest git. Should have been clearer earlier.

And yes, same error.

[Roonil]

Looks like I really need to give Ubuntu some more time. Can you also verify that the libcyaml-dev package is not present on your system? It really shouldn't happen on the git version of the package.
