Thanks alex, I'll check that out.
ATM the interface is brutally slow, when I click something it takes 10-20 seconds until it reacts.
Will report if I find a solution.

Cheers,

Tom

Ah, I see you figured it out. My bad! This particular issue might be due to driver versions. I had this too, and downgrading to 580 drivers fixed it. There's a Reddit post I learned from that tells you how. I can't share links here, but you just need to do the following:

downgrade command in terminal:
sudo pacman -S lib32-nvidia-580xx-utils lib32-opencl-nvidia-580xx libxnvctrl-580xx nvidia-580xx-open-dkms nvidia-580xx-settings nvidia-580xx-utils opencl-nvidia-580xx


revert back to current:
sudo pacman -S linux-cachyos-nvidia-open linux-cachyos-lts-nvidia-open nvidia-utils opencl-nvidia lib32-nvidia-utils lib32-opencl-nvidia nvidia-settings

Hey,

from this discussion I take it, that the latest Houdini 21 should run on CachyOS with KD Plasma, right?
I installed it with no problems, but get a segmentation fault crash when I try to start it.
Anything else I need to install to get it to work?

I'm pretty new to CachyOS (2+ days), trying to find out if I can finally move to Linux after decades on Windows... :-)

Cheers,

Tom

Don't give up! Or if you do, that's okay too LOL. I will say it took me a good while to start to really feel comfortable with Linux (CachyOS being my first distro). Trying to figure out Linux while trying to figure out the complexities of getting Houdini working properly can be a lot.

I'm wondering if it might be a drivers issue? Did you install the gaming packages? What GPU are you running? I'm running a 5090, I installed the gaming packages, and didn't have any issues launching Houdini out of the box.

Can do a big thumbs up for HQueue. I used Google Gemini to help set it up, plus a lot of old fashioned googling. There's a great video on YouTube about it too: https://www.youtube.com/watch?v=838z9v17ThI [www.youtube.com]

My use case is I have four machines: one being a workstation running Linux (CachyOS), a Win 11 desktop, an Ubuntu Server, and an Ubuntu Server VM on my 64 core Threadripper running Proxmox.

The Ubuntu VM hosts the HQ Server and is a client with GPU pass thru. Files are mapped cross platform so my Windows machine picks up just fine from my Linux jobs. They all render and simulate concurrently with no issues.

That being said, there are a lot of quirks to getting it working. I basically did all of this while also learning Linux and there were times it was a PAIN. Be prepared to spend a weekend or two to really get it figured out.

Like I said, Gemini (and sometimes Claude, though I found more success with Gemini) is very helpful in finding answers to random issues, like when you get an error in your HQueue log, and the AI helps you find out which part of Linux is borked, etc.

All that to say: I think HQueue is a solid choice, if not the best choice, for running a Houdini-only job management system. We use Deadline at the studio I'm at and it's really great for a lot of things, but I think it's hugely overkill for a two machine environment where Houdini is the only thing you'll be using it for.
