I have been using openSUSE Leap 15.6 as it works with the amdgpu-pro driver. And that driver is needed as you will run in the problems using the mesa open source drivers.

Leap's KDE Plasma desktop comes with both wayland and X11. The X11 i needed for the driver. Wayland does not render.

I have some issues with Vulkan reverting back to OpenGL in Houdini at the moment. But i will report back if i get that fixed.

vulkan has indeed also been problematic. It's been making houdini more unstable. I also reverted back to openGL.

I was honestly thinking that Maya will actually be last to got Wayland update. Seems like it wasn't up to Maya at all.
Since recent linux updates kernel and nvidia driver updates Maya is working just fine now on Wayland.
But Houdini got even more unstable then it was. So just wondering if it is up to SideFX or something to do with NVidia??

Not sure if it is due to latest drivers but I've just run Houdini under Wayland on Nobara 39, nvidia 4090 and latest 555 nvidia drivers and seems to work just fine. Nothing special just fired it up

Hello there,
just checking how is it going for you with Houdini in Wayland on 555 NVidia drivers after 10 months? Are you still on 555 drivers? Or did you switch to X11 with more up-to-date drivers for Linux?

Curious to know how did it go for you over longer span of time. Thx

No luck at all, crashing nonstop, I had to put X11, after all, to be able to do anything, unfortunately, seems like we can only hope for some Wayland support no H21.

Hmmm, I see.

Well Nvidia and Redhat are on the boat regarding Wayland development. Which I hope is a good thing

Well yea, Fedora kicked X11 since 41, now 42 is almost out, and Fedora is RH testing ground.. there is still Rocky and Alma that will stick to X11 for a while I guess but everybody else is removing X11.

RHEL 10 is around the corner. Officially dropping Xorg but maintains backward compatibility with X11 clients through XWayland.

RHEL 9 which still has X11 and Xorg will be supported until 2032. I assume studios are not in rush with this since Rocky Linux 10 is not even out. And they can use Rocky 9.

So Houdini has 7 more years until it starts supporting Wayland

Well I've got Rocky Linux 9.5 at the moments that solved problem I guess.. It have both Wayland and X11 integrated so. will live for a bit more. But still would be great to have Wayland support, Blender got it for couple years now...

Hi,

First I'm not a pro, just a hobbyist.
I'm on Arch Linux and KDE 6.4, only modeling stuff and some rendering test with Karma xpu, nothing fancy but since a few weeks no more crashes at all even after hours of work. Before Houdini was unusable on Wayland for me.
I think that Arch is not used in production pipeline, just to say that it seems that the Houdini crews are on the good way.
Thanks for your time.

That sounds promising.. will have to test as well!

Can confirm, on my arch box with Gnome on Wayland and latest NVIDIA driver, houdinis qt6 build seems to be quite stable.

I’ve been following this topic closely. As soon as I saw MattiBRND’s comment, I tested it right away on Fedora 42 with GNOME. Previously, just typing "pig" in the search box would cause a crash — but not anymore! I also opened a complex project, and all kinds of operations ran smoothly. It’s such a joy!

Yes, it’s so good! I’m sure there are edge cases still, but as soon as H21 will have official support we should be golden. Are you guys using the Vulkan or OpenGL viewport?

That’s great news. I am now waiting for PCoIP apps getting Wayland support for remote GPU sessions. Which will probably not happen anytime soon, lol 😅

I'm using Vulkan, no problem

Vulkan too, no problem

still no luck here, crashing non stop.. unusable...

I have very similar setup, but with RTX 4070Ti and Ryzen 3900x cpu.
Houdini works flawlessly.

OS: Nobara Linux 42 (KDE Plasma Desktop Edition) x86_64
Host: X570 Creator
Kernel: Linux 6.15.7-200.nobara.fc42.x86_64
Display (WAC1057): 3840x2160 @ 60 Hz in 32"
Display (LG TV SSCR2): 3840x2160 @ 120 Hz in 72" *
DE: KDE Plasma 6.4.2
WM: KWin (Wayland)
CPU: AMD Ryzen 9 5950X (32) @ 5.09 GHz
GPU 1: NVIDIA GeForce RTX 4090
GPU 2: NVIDIA GeForce RTX 4090
Memory: 11.68 GiB / 125.71 GiB (9%)

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
