How do I use this?

[UnknownUser95]

I have found your post on the KDE subreddit and it a go, however I only get a black screen. The store description nor the README don't give any instructions or requirements either.

So I'm asking here: Selecting a shader just gives me a black screen. The iChannels are unused (default state). Are there any requirements for this (i.e. do I need an extra package)? In your video I saw the iChannels being used. Are they important? What is their purpose for a shader? Are they required for shaders to work?

You probably need to include QSB in your path as the readme mentions, grab the plasma6 specific release here, and on top of that he's got a case issue in the filenames. it couldn't find the PS3 shader because it was specified lower case but the file was capitalized.

Once I had my path set and made a copy with the right name it worked.

That said, I don't know if there's a way to select which shader runs right now, short of only compiling the one you want; the UI is not currently in a functional state.

That's no knock - it looks like it'll be solid after an update, and the shader performance once I got it running was very reasonable.

I look forward to future releases.

@UnknownUser95 Getting a black screen is not normal.

1. Did you install it from source or from the "Get new plugin" button in KDE wallpaper's plugin option?
2. What GPU are you using?

I've compiled the shaders using Vulkan-style for 100 es, 120 and 150, so it should work with most...

@jkerls You can select which shader actually, you right click on your desktop and configure it here:

I've heard Plasma6 added an option for wallpapers in System Settings though and I don't think it shows up right now, I will be adding that function too if possible.

Thanks for that, I will fix it

@UnknownUser95 Just for clarity's sake,

iChannels are important for some shaders, it's a case-by-base basis depending on the shader. Some shader requires to be passed an image, for example, receiving noise input via a noise texture/image. Others don't.

For example, Rainier Mood uses iChannel0 as a background image (so just choose a wallpaper image you'd like) and you'll get a nice rain effect on top.

@y4my4my4m Yeah, I have that dropdown, but it doesn't actually select anything, it runs the ps3menu shader no matter what. And no change to anything on that page ever makes the Apply button light up.

[jkerls]

Okay, but closing and re-opening did seem to apply one. I'll have to experiment.

Edit: And now it changes them on the fly when I select one. It wasn't doing that before. But I'm not complaining!

Strange... The PS3 one is the default one indeed. It means that somehow that value couldn't be written to when selecting another shader? 🤔

Edit: ...Oh I did capitalize it huh 😓

I've updated the release package to account for that (both KDE store and github), please reinstall if you run into a problem again.

Edit: Also, I've tried from Settings > Wallpaper. It doesn't work, you have to do it from right clicking your desktop.

I will update it.

1. I got it from the KDE store.
2. A RX 6900 XT.

I now had the time to check if the update works and yes, it does!

Completely forget to say thank you for the clarification!
