Just wondering if there are any news or idea if this will be possible at some point? Are there any plans to support Wayland at least in the next mayor version?

I was hoping for this too, at least for me I can launch Houdini on Wayland but it is very unstable.

Exactly it is crashing non stop.

I am on Fedora 41 KDE plasma . Houdini on Wayland crashes non stop. Also I couldn`t manage to configure my wacom tablet pen buttons. I just want to switch right click with left click . So now I go back to X11 then Houdini is ok and I can switch wacom pen buttons.

Now I have dual monitor issues. My laptop is 1080p and my second monitor is 4K. Dual monitor resolution setup doesn`t work and it is annoying. But I think it is the lesser evil and it is easier to manage so I stayed on X11 for now.

Anyone know if there is any Sidefx plans to implement Wayland compatibility on Houdini?
Would be nice to have it.

i've contacted the suport team end they said

Our developers have told me that we are planning on adding support for Wayland in the future. Our plan is to enable Wayland support in the Qt 6 build but only in the Houdini 21.0 release. I don't believe we will enable it in Houdini 20.5.

it's X11 for us until houdini 21 comes around

Honestly it was expected..
Soooo....
21 release day? )))

Seems like qt6 version works fine with wayland as well... will test more but so far seems to be rather fine.

Which build are you using?
It was pretty unstable for me couple builds ago.

20.5.473 qt6

It was same to me couldn't have it up for longer then couple minutes. Now it is not crashing. Still some bugs around some tooltips and similar, didn't get to play too much to discover more but still more stable then before for sure.

EDIT: I was a bit hasty on this one.. still crashing same as before so ignore optimism please

So.. linux peple,, how do to you deal with this issue?

Back on windows? Stuck on any non Wayland distro left, rocky or similar...
I've got back to windows but hating it every day.. death by thousand microsoft cuts

Managed to install X11 again but seems like xinput command is no longer available and cannot be installed, without it my cintiq is unusable now as well... under Wayland cintiq support is surprisingly great now.
Suffering slowly on windows at the moment ...

I installed Xubuntu in the meantime on my my PC.
After I finally got everything working (mostly installing NVIDIA Drivers and QT)
It works pretty well so far.

Is it on Wayland or X11?

Is it on Wayland or X11?

Xubuntu comes with Xfce which is still on X11 but preparing for Wayland.

That is why it works. X11 is fine. Wayland I problem. And there is no more X11 on Fedora, Nobara... and many more. Manualy installing X11 is possible but brings ton of other issues with updates and others so not an option any more I'm afraid. Only hope seems that H21 will support Wayland..

yes, you are right!

I tried 3 different versions/distributions (ubuntu standard with xfce installed after the fact, fedora and then xubuntu) to get it working.

Do we know anything about 21 yet?

I am using Houdini with X11 on Fedora with no issues, I just enabled X11 and got no problems so far.
But this should be addressed somehow, I am not sure if it is a Linux or a Sidefx thing.

I'm running Pop!_OS and so far so good, I'm eager for the support to wayland to arrive as well but I rather be stuck with x11 than going back to Windows.

Well Blender works on Wayland no problems at all wonder whats going on there...
Wierd one Maya 2024 seems to be fine now but Maya 2025 is messed up (black viewport and animation graph editor.
And Houdini is crashing non stop

Soo all this X111 and Wayland is messy and never figured out actually what is reason of it to work on one side not working on another...

Yes we need a wayland support in houdini for linux it a pain to use x11 now. And in cant move all of my workflow on windows
