I saw a note about new versions of nvidia drivers causing issues, is there any ETA to a proper fix?
And yeah it is being pretty unstable for me on Linux even on X11, is it just me?

I just checked I don't even have version 580 on repositories available anymore, I know I could do manually but that would not be as I would say ideal like a proper fix.

Hey mzigalb. I am on Rocky Linux 9.8 (X11) and the Nvidia 610.43.02. I am not seeing any issues. I just finished a project in H22 with zero issue. No crashes at all. I have also used H21 without issue as well. Are the crashes happening at a specific time, specific operation?
Here is the instructions I used to install the driver.
https://docs.rockylinux.org/9/desktop/display/installing_nvidia_gpu_drivers/ [docs.rockylinux.org]

I did not had issues on the same system which is fedora with H21.
With H22 I have constantly freezes and crashes in the same system.

I would make a support ticket and work with their support staff to fix your crashing. Good Luck.

Just checking if it is just me first.

Also they already know that is unstable or they would not post about the Nvidia instability themselves, I am just checking if there is any ETA to fix this.

For what I have seen so far it seems this instability is more on the Linux side unfortunatelly on Windows it seems more stable.

It's unfortunately not an easy thing to give an ETA for. When we run into driver issues, we either need to come up with a work-around, or wait until NVIDIA fixes the issue on their end. Both of which can take some time.

i uppdated to new version when it arrived (a week ago i think) linux 580.173.02, ubuntu 22.04

h22 works good, but the big uppdate was that unreal 5.8.1 behaved much much better on linux.

Im' currently having issues with Fedora and Houdini 22.0.418. The issue is that it crashes before loading the UI. If I disable OpenCL then it opens normally but COPs is slow

Basically I'm doing this
cd /opt/hfs22.0.418
source houdini_setup
HOUDINI_OCL_DEVICETYPE=CPU houdini

My current nvidia drivers are 610.57.04.

I hope that helps.

I’m running Houdini 22 on Pop!_OS with the NVIDIA 580 driver branch and OpenCL works fine here.

Since Houdini starts for you when forcing HOUDINI_OCL_DEVICETYPE=CPU, I’d strongly suspect the NVIDIA/OpenCL side, especially since you’re on 610.57.04.

I’d try rolling back to the 580 branch first. That’s also the branch SideFX currently recommends for Houdini 22 on Linux.

Well having to cut down features like OPENCL and roll back drivers just to make Houdini just work is not ideal and beside other reasons Houdini is not the only software that is needed to be run on the system, on Windows I don't see the issue.

I found the issue for my case. According to Claude Houdini was trying to create the viewport shared context GL+CL with hybrid graphics. Basically OpenGL was tied to the intel GPU of my laptop and OpenCL to the Nvidia GPU. So the snippet to run Houdini with both context run by my Nvidia card is

cd /opt/hfs22.0.418
source houdini_setup
__NV_PRIME_RENDER_OFFLOAD=1 __GLX_VENDOR_LIBRARY_NAME=nvidia __VK_LAYER_NV_optimus=NVIDIA_only houdini

I hope it helps others.

The issue was fixed in the last production build 22.0.429
