Hi all!

I know that AMD has software for controlling RGB on Windows. I found some old threads where someone suggested disconnecting the LEDs themselves, which is not something I'm willing to do with my 2-day old card.

I also would love not having to switch to Windows just to turn the bloody RGB off.

I've never used OpenRGB and I don't quite understand their compatibility guide for the 9070, so I'm not sure if it's doable there.

So! Does anyone here have that card and was able to disable RGB on Linux?

As a sidenote: I just realised that my OS sees two GPUss - the dGPU and the iGPU. Is there a way I can turn iGPU off so that it doesn't get in the way?

Any help appreciated!

Oh, I should probably mention - I'm on:

OS Garuda Linux x86_64
├ Kernel Linux 6.13.8-zen1-1-zen
├ Packages 1366 (pacman)[stable]
├ Shell fish 4.0.1

DE KDE Plasma 6.3.4
├ Window Manager KWin (Wayland)

For the iGPU issue, there should be an option in your setup utility/BIOS on your motherboard that either allows you to disable the iGPU entirely (usually in the settings for CPU or chipset, can vary from board to board), or (in the case of my Asrock board at least) there is a "dGPU only" mode that automatically disables the iGPU when a dGPU is detected. For the RGB, since the 9070XT is a partner only card (so many different manufacturers make them), the RGB implementations can vary a lot between models as there is no standard design (would be wise to edit your post to say which specific brand and model of card you have in case other people with that brand have experience with it). It might be worth just installing openRGB anyway and seeing what it detects automatically, as it could pick it up.

I would rather disable it on the OS level because I'm slightly paranoid that the dGPU dies at some point and then I can't even access UEFI, because the iGPU is disabled.

I can't guarantee this, but I think most motherboards would fail safe if the dGPU is removed and give you the UEFI over the iGPU. If you're worried about it, you could always change the setting, then remove your GPU to test what happens when you try to pull up the UEFI.

In general, I'd suggest being a bit more curious and playing around with stuff, even if more carefully. Like you said you didn't understand the options for OpenRGB and it sounds like you didn't try installing it at all to eliminate it as an option before posting. I understand being anxious but you're not going to learn much if you're not willing to muck up sometimes. It's not like an app like OpenRGB is going to break your GPU or anything.

Man, I'm 40, my 9-5 job is being curious, testing and retesting stuff. When I'm home, I just want to play some games....

Yeah. I've learned (through curiosity and testing, btw) that it's super easy to break stuff in Linux, so I was a bit weary of installing third party software that does "something" to control the LEDs on a graphics card.

I did test it out yesterday, though. Sadly, does not recognise the GPU. It did recognise my mouse, though, which is neat.

That's the thing - I'm in a state where stuff works and is fine. That came after five reinstalls and three distros. Linux is not Windows - it's fairly easy to do some unrecoverable* damage if you don't know what you're doing.

* yes, I know, technically everything is recoverable, but that requires knowledge and time, neither of which I have for this kind of stuff.

From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.
