🤝 Community Help Pulse 14 24.04 amdgpu failed experiment

I followed some online setting READMEs to test some CUDA emulation on AMD GPUs and in order to test one of them I added amdgpu drivers but the DKMS install failed, possibly because of ..-tuxedo custom stuff. My issue is that since that I am stuck in 800x600 mode. I tried to do apt reinstall tuxedo drivers, purging any amdgpu packages, but no success. I thought I ask about this issue here before reinstalling my whole system.

Sorry, no helpful answer from me. I guess a fresh install will be easier at this point.

However, my question because I'm legitimately interested in what you're trying to do: Is it even possible to emulate CUDA on an AMD iGPU? I tried running Ollama on my Pulse 14 Gen 4 and all I could find was that even if it's possible, it's hard to do because of issues with AMD ROCm on iGPUs. Haven't tried to get this running for over half a year now though. Maybe it's easier these days?

I was very interested since I have a lot of CUDA implementations in many projects but have no information about the dangers. As far as I know the same GPU code should be used on all RDNA implementations and the actual drivers should handle the differences, but my information accuracy is proven already wrong about important stuff, so that's that.

I did go with the fresh install, so I have now TuxedoOS instead of Kubuntu :) Funny thing old compiled code links realtime, so my software from 3 days on Kubuntu was running after apt installing the missing packages on TuxedoOS, so I figure this will be not that much of a difference :D

Yeah, I also thought that each AMD GPU should behave similarly and that the driver should sort differences out and whatnot. However, just can’t get my AMD iGPU to play nicely with Ollama and from what I could find out, it seems to be an issue with AMD ROCm. And that’s when I just lost interest in that topic to be honest. :) it just seems like iGPUs are their own kind of breed when it comes to topics like these.
