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.
I’m having the same issue with booting an Fedora and Arch USB. I also have to set nomodeset
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.
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.
