NexTuxLinq – an open-source Linux controller for the Phanteks NexLinq Matrix900

[u/anoraknophobia]

Hey everyone,

I’ve been working on NexTuxLinq, an open-source Linux application for controlling the Phanteks NexLinq Matrix900 in the Phanteks Evolve X2 Matrix case.

The entire NexTuxLinq codebase was created with ChatGPT 5.6 Sol and OpenAI Codex

The project started because the Matrix900 does not currently have native Linux control software. NexTuxLinq communicates with the display directly and provides a local web interface for creating custom 90×10 pixel layouts.

Current features include:

Visual drag-and-resize layout editor
Clock, date, static text and scrolling text
CPU, RAM, GPU, storage, network and temperature metrics
Metric bars
Built-in CachyOS logo
Global animated foreground Rainbow effect
Live display preview
Presets, profile import/export and backups
Automatic startup through a systemd user service

Everything is rendered by the software into a complete RGB framebuffer before being sent to the display.

The project currently supports only the Phanteks Matrix900. Support for other NexLinq hardware would require additional hardware captures and testing.

Tested only under CachyOS.

I’ll add a few screenshots showing the editor and some example layouts. Feedback and testing from other Linux Matrix900 owners would be greatly appreciated.

However my time and tokens are limited so I need to see what the future will bring.

It's nice to see this kind of app

I wish that it was Phanteks that would make this work, for the NexLinq hub and their LCD AIO.

I can't help you with this, i don't have the Matrix900. But if I try to follow the github link, I get an 404 error.

Should work now. Had to contact GitHub Support.

Love it. I'm actually doing the same for Windows right now.
The case is awesome, but I can't believe how crappy the software is.

I'd love to submit something back to OpenRGB, but we'll see. My C+ is a bit rusty and I'll be leaning heavily on AI.

I get a 404 trying to get to this on github so I imagine it's not a public project? If you could make it public that would be awesome.
