amdvlk, any reason you’re not using the MESA driver, RADV?

What is your:

1. Kernel
2. Linux-firmware
3. Mesa

Versions?

Additionally, what does the kernel logs tell you when you get a green screen?

There is a patch-series that is now merged into 6.15-rc1 that exposes more i2c/RGB controllers on the GPU side for AMD cards, so that kernel + OpenRGB (as others have mentioned) might be a solution down the line

Patch series for reference: https://lists.freedesktop.org/archives/amd-gfx/2025-January/118399.html
