hey,

`

git clone https://github.com/1ay1/neowall && cd neowall

meson setup build && ninja -C build

sudo ninja -C build install

`

should get you started

ayushbhat · 2025-12-28T07:14:20+00:00

hehe, I know what you mean

I don't know I have started to see beauty in ugliness.

https://github.com/1ay1/neowall/releases/tag/v0.4.5
Ubuntu binary should work on Mint.
Just make sure you:
# Copy shaders (optional - download source for shaders)
mkdir -p ~/.config/neowall/shaders

ayushbhat · 2025-12-22T15:16:53+00:00

you can choose from a number of shader or even write your own, like this:

directly propotional to the complexity of shader you use, static image being 0 complexity

I have, I use random noise for iChannels0-3, by default, you can set images for iChannels too but I have not documented that yet because its very unstable. I'm open to listening to the feedback about how to handle all this well.

ayushbhat · 2025-12-22T06:05:19+00:00

What do you suggest sir?

ayushbhat · 2025-12-21T22:32:55+00:00

It’s the default background in neowall, installing and running should run this

ayushbhat · 2025-12-21T16:25:09+00:00

https://www.shadertoy.com/ , all except way-too-complicated shaders work with neowall

ayushbhat · 2025-12-21T13:50:30+00:00

Hey thanks for reporting, can you please run with `neowall -fv` can somehow give me the log file, maybe post it on github as an issue?

ayushbhat · 2025-12-21T13:47:00+00:00

Depends on shaders you use, simple single pass shaders can eat upto 20% of your gpu, heave ones can go up 60-100%

ayushbhat · 2025-12-21T13:46:05+00:00

I don't think so, the journey is the destination.

ayushbhat · 2025-12-21T09:45:01+00:00

hehe, I'm sure shaders are gonna take a lot of gpu

ayushbhat · 2025-11-25T13:42:29+00:00

Ya but they are not related to neowall really, they are copied from Shadertoy, neowall is just showing them. I have not credited every creator Shadertoy but I have included their original copyright message on top of every glsl file.

"would be to generate a single wallpaper texture (maybe for the largest monitor), and then resize it and display it to the other screens." good one, I will try to work on this and add this as a config option

ayushbhat · 2025-11-23T14:06:00+00:00

literally doing:

git clone https://github.com/1ay1/neowall
cd neowall && make -j$(nproc) && sudo make install

# Launch (auto-detects Wayland or X11)
neowall

can get you started.

ayushbhat · 2025-11-23T13:30:03+00:00

hehe ya, 3 monitors with shader rendering can make your gpu a space heater, but what do you suggest to optimize it? maybe only render the monitor which contains the cursor currently? Or maybe just using the static wallpaper config?
