I’m a long time AMD user both my GPU and CPU. I have a powerful enough PSU and a b550m-plus mobo.
I’m looking to do gaming, light AI work, computer programming, running Docker server services.
I have a Radeon 6900xt, but it doesn’t work well with Linux anymore. amdgpu fails to load, and I can only boot by adding nomodeset to my boot entry.
With ArchInstall I even tried reformatting with xfs, ext4, btrfs, without encryption, with and without LVM, selecting both ATI OS drivers for all GPUs, and drivers for AMD gpus, with systemd-boot and grub.
Even Fedora on USB only boots with nomodeset.
Windows seems to boot fine.
I assume it may be a problem with system reading the drivers from the GPU.
I have onboard HDMI for graphics, but I’ve never got it working.
tbh, my 6900XT was too powerful anyways. I do game in 4K with my 55" TV on the highest settings, but it seems I was still barely using the GPUs full potential.
Funny enough, I seem to have had more problems with high end GPUs in the past than low end GPUs.
Hang on…
Just because no one has asked it yet…
Are you only using a HDMI cable and have you not tried a display port cable?
FYI: The “HDMI Forum” didn’t want to allow open source implementations of HDMI 2.1. They wanted to charge people a fee for using it. This is why people use display port, it has no fee and it usually has newer feature support earlier.
I dont have a monitor with DP, but I could look into trying a friends monitor. I’ve only been using HDMI and HDMi 2.1

Super weird. I also have a 6900 XT and have never had any problems on linux. The fact that you’re having problems with the GPU on multiple systems makes me think this is a hardware issue. Windows probably only works fine because it may be using the onboard graphics instead of the 6900 XT.
AMD is the most compatible and best supported for linux. You don’t need to install any drivers or anything for AMD as the official drivers are included in the linux kernel.
on arch you still need to install the Radeon Vulkan driver, but that’s just a userspace thing
also for blender you need hip and hip-rt iirc
they’re way easier and nicer than nvidia though
This makes no sense. That card should be a prefect fit. If you cold boot does it crash and restart in a loop?
Cold booting does the same effect. Sometimes I’m able to bootup the driver. But after a reboot, the same problem always recurs.

I disagree with others, this seems like a software issue. Specifically a config one. Its a strange coincidence that both a 6900XT and your IGP would be misbehaving.

This is also strange, as 4K should be rather stressful. And I’m pulling this thread because AMD GPU prices are awful now and you should really keep your 6900XT if you can.
So… have you tried start fresh? EG booting some other distro from a USB and see if it work alright?
Have you changed anything specific in your BIOS?
I’m having the same issue with booting an Fedora and Arch USB. I also have to set nomodeset
Oh, and one other thing I thought of:
Your IGP HDMI may not work because, with the graphics card, the BIOS might disable it by default. Mine does this, but its configurable.
What about a bone stock CachyOS image, with its default graphics config and no boot changes?
Again, I am not trying to be rude, but I am (out of personal experience) suspicious of whatever configurations you might be making and am interested if a ‘default’ config like they ship with gamer distros works.
I agree with the other poster this seems like a hardware issue.
- Start with a general battery of hardware tests.
- Memtest for memory. One or two errors in a full run is OK, more than that is not. A full run will take a few hours, just run it overnight.
- Furmark for GPU. Look for visual glitches or crashes.
- Prime95 for CPU.
- If those fail to point out the issue. Swap components into another system. This will allow you to eliminate (or confirm) them as the issue. Example, does this GPU have issues in a different system?
Have you ruled out the GPU itself is not physically defective? I’m rocking a 6700XT and gaming in 1080 like a champ. I’m lazy so I’m running Mint though.
Have you updated firmware for the card and your BIOS lately?
Edit: also, who makes the card?
Are you saying I can update the firmware inside the GPU? I’ve never heard of that. It’d a Gigabyte gpu.
And the mobo firmware fully updated. I’ve tried with both recent versions of the Asus b550m-plus bios firmware.
Might as well also try out Debian 12 and Ubuntu.
I have a 7600 and it works well with Debian 12. Also, my CPU doesn’t have an iGPU, so can be sure that’s how it is working.I love Debian. Literally the worst possible choice for GPU drivers.
But it works.
