I'm trying to have linux with as least as possible manual work involved and just install and use

Yes, that's right, Nobara works out of the box with nvidia, but the installation of Archlinux is really simplified with the script Archinstall, just do not forget to install with the script or at the end of the installation opencl-nvidia for Davinci and Houdini.

I need maya, houdini, davinci resolve.

I know it's not the good place, but it can help someone : to install DaVinci on Arch, just download it, install "libxcrypt-compat", install davinci, and if davinci doesn't start you just have to delete the files between the {} or displace them in a folder like "_disabled" (I think it's a secure way). You can do it manually or with this line in a terminal :
"sudo mkdir /opt/resolve/libs/_disabled && sudo mv /opt/resolve/libs/{libglib-2.0.so*,libgio-2.0.so*,libgmodule-2.0.so*,libgobject-2.0.so*} /opt/resolve/libs/_disabled", (where "sudo mkdir /opt/resolve/libs/_disabled" create the folder and the second part moves the files in that directory)

It works for me, and you do not have to use AUR.

For Maya, I don't know, I'have tried Unreal and it works too.

I don't want you to think that I'm pushing ArchLinux too hard against others Linux distributions, especially since I'm not an expert on Linux, Houdini, or DaVinci. I'm just an amateur, explaining what seems to work for me. And it's true that ArchLinux is the most stable version of Linux I've used so far, but yes, it requires a little more work at the beginning. I just want to help, as a lot of Linux users helped me.

And still unusable. Sometimes it lasts longer, sometimes crashes after couple minutes.
I tried default and qt6 versions as well.
Maybe I will try with just 1 monitor attached... who knows

Hi,

I made a quick install of Nobara to give it a try (iso wiht nvidia and kde), and same problem as you, Houdini is unusable. Blender seems to work. Nobara is based on Fedora, it would be interesting to know if Houdini crashes too on Fedora ?

On my system, Houdini works fine at the moment. But I'm not a power user as you, a lot of modeling and a bit of Copernicus to learn it and some rendering stuff. But no crashes anymore for several months now.

Do you know CachyOs ? It's a fork of Archlinux for gamers, it works out of the box, very quick to install and easy to configure. Actually, I would be interested to know if an impressive configuration as yours, with two Nvidia cards, works on Archlinux ?

Are you guys using the Vulkan or OpenGL viewport?

I'm using Vulkan, no problem
