Tried to use something other than ubuntu
TL;DR: I worked for about 23 days, then an update May 5 broke my Python setup (specifically ComfyUI + ROCm)
I’m a web-developer and have been using ComfyUI to generate placeholder images on websites I build for clients. ComfyUI on Mac is painfully slow. In February comfyUI added support for ROCm, so I waited a month for them to work out the bugs then built a PC (Ryzen 8500G, Radeon RDNA 9070, 32GB RAM)
I decided on CachyOS over Arch because I wanted something that JUST worked OOTB. My biggest issues with Arch are
running FDISK to configure my SSD just isn’t fun
running WPA supplicant from the command line to setup Wi-Fi also isn’t fun
and trying get a compositor and Desktop Environment working from the command is error prone and frustrating
CachyOS issues
CachyOS is super cool. I honestly really liked it. But...I had these problems that I didn't know how to solve
CachyOS misidentified my GPU’s ID as gfx1101 instead of gfx1201
VRAM not clearing between model loads resulting in crashes and OOM errors
PyTorch would be super slow on first render with ComfyUI
TensorFlow would error out when running a training set
unable to use the ROCm amdgpu drivers resulted in instability
I use the iGPU to run my display and use all 16GB of VRAM on the 9070 to be used for PyTorch, running LLM inference, generating images using ComfyUI, training image classification using TensorFlow.
CachyOS had a hard time with this - almost every reboot after an update there would be no display out on the iGPU. I’d have to connect the DisplayPort cable to the dGPU, log in, shutdown, unplug for 10 seconds, plug DisplayPort cable back into iGPU then turn PC back on. This worked about 100% of the time. And honestly, things worked pretty decently, certainly faster than my M3 MacBook Pro, so I didn’t complain too much thinking it’d be fixed in some update.
Then May 5 update. I’m not sure exactly what was updated but my system would NOT display anything on the iGPU (not even BIOS/UEFI). ComfyUI crashed with sqlalchemy errors and wouldn’t even run. LlamaCPP using ROCm also failed to run (GPU hang errors)
I lost a day of work. I had to download Ubuntu 24.04.4 and install it. 2 hours later, everything was working fine. I was able to use the amdgpu drivers from
repo.radeon.com. Things became super stable, a 1650x1080 render completed in about 17 seconds using z image turbo (down from 27 sec) , longcat image editing took about 30 seconds (down from 40 seconds)
I get why people don’t like Ubuntu, but honestly, I have to use something stable for my work and Ubuntu works. I’m glad I tried CachyOS, it’s cool, but for me, Ubuntu is a better fit
