Guys, is it possible yet to run win apps on linux?
Especially Adobe ones...
Full Version: Houdini on Wayland Linux
@coccarolla It is possible. But especially Adobe/Affinity may have noticably worse performance or UI glitches. It may also take hours of your time to properly set it up. Definitely takes a technical person to do it. It's safer to learn native alternatives.
I've got Houdini 21 running really smooth with the latest Nvidia drivers (RTX 4090) and Wayland (KDE) on Arch.
With the exception of the same mousewheel scrolling issue in the network and param views.
I went down the rabbit hole figuring out the cause of it, and most likely the culprit of it is Wayland's Qt6 that sends mousewheel event values in degrees instead of pixel shift. Hence X11 works fine.
I naively hoped disabling smooth scrolling in KDE or remapping it to increments would help, but had no success.
Hou 20.5 (QT5 version) works fine.
If anyone managed to solve that issue please share
In the meantime I can only hope SideFX will release a Daily with a fix *pretty please*

Is it possible to run on wayland from terminal with --ozone-platform=x11 parameter to switch to x11 only for houdini ?
I didn't check that and have no houdini installed, will that work ?

Erik WsI think ozone exclusively belongs to the chromium framework and is not associated to anything UI related houdini-wise

Erik WsThanks for the suggestion, unfortunately this didn't work. As MattiBRND mentioned - ozone is for Chromium, we would have to force QT's X11 instead. (I have no clue myself)

But, I tested Houdini 21 under QT x11 like this:
unset WAYLAND_DISPLAY QT_WAYLAND_RECONNECT export QT_QPA_PLATFORM=xcb /opt/hfs21.0.440/bin/houdini
Confirming it's running under x11 (I think this confirms it
)# grabing Houdini's process ID pidof houdini-bin # checking linked sockets/libs that have wayland or x11: lsof -p "HOUDINI PID" | grep -E 'wayland|X11' # My output shows X11 libs only: /usr/lib/libX11-xcb.so.1.0.0 (path dev=0,35) /usr/lib/libX11.so.6.4.0 (path dev=0,35)
Does this suggest that Wayland, or at least QT under wayland, might not be the cause of the issue after all? :/
Any other ideas?
I don't know... I installed Houdini Apprentice (I don't think license type matters for wayland)
it runs smooth across all tested scenarios, except scrolling issue in node editor which just doesn't work (no reaction on mouse wheel), but I can zoom with RMB, it's little bit annoying but nothing that is real trouble.
My System is Ubuntu 24.04.1 on newest stable nvidia driver 580.82.09 + vk viewport.
What I need to test it with, what else problems wayland might have on houdini can you please share experience?
Can Sidefx somehow fix that scroll issue? But I don't think that's their side of work .
Anyway, it runs unexpectedly well. Also I feel Ubuntu itself little bit different now, it's kinda faster across all apps I have here!
in short among all drivers I had 580.82.09 is my favourite so far.
Fingers crossed!

Hey Linux guys!
So glad I found this post
I've been running cachyOS/hyprland for a while, H20.5 worked pretty much flawlessly out of the box, but H21 has a couple of issues.
One is the mouse wheel which is known (only works in the viewport for me), but another much worse bug I'm experiencing is with the tab menu... after a while, apparently randomly, it just freezes. Some times after hours, some times after minutes.
The other thing is any drag and drop function inside Houdini is broken - only in houdini tho, so it's not a hyprland thing apparently.
These only happen on hyprland, and not on plasma/wayland for example.
Any idea what I could try to fix it? Besides waiting for better support for the whole wayland env

The main thing that has changed in this area is the use of Qt 6.5 from Qt 5.15 so I'd hazard a guess is to see if other applications that use Qt 6.5 have the same problems with hyprland as well. But in Houdini's case, it still doesn't use the Wayland backend. If it's running on Wayland, it's because it's using the xcb backend with whatever Xserver emulation that you're using with wayland (probably XWayland?).
if it is using xwayland why we still have a problems? with mouse scroll for example, since houdini is completely ok on x11.
if h is using xwayland and not wayland how to force it to wayland ?

Because xwayland is not x11. If you've read the above posts, someone mentioned that xwayland used to far worst and Houdini was not usable under it before. I'm guessing that there might also be differences in hyprland/xwayland as well.
if h is using xwayland and not wayland how to force it to wayland ?We cannot force Houdini to use wayland because that requires the Qt wayland backend to be shipped with Houdini which is currently missing.

So, a couple days after my previous post the tab menu bug started showing in plasma as well, even if much less than on hyprland... superweird...
BUT
After reading this I tried installing the latest daily version, qt5 variant... for now all I can say is: the mouse wheel is back!!
Hopefully the tab menu bug won't show up, I'll report after some usage

qt5 fixes the mousewheel issue on KDE (EndeavorOS / Arch).
Yaaaay. Thanks SideFX.
I will stick to the Daily for now.
I hope this will help ironing it out and will eventually transfer to an LTS release.

Latest build 21.0.512
I don't think it fixes it. I tried Arch and Ubuntu/Wayland
Mouse wheel still doesn't work :S
Erik WsMake sure you're running the qt5 build of Houdini.
I don't think it fixes it. I tried Arch and Ubuntu/Wayland
Though the qt5 version seems to have issues here with losing keyboard focus
(If I remember correctly)
For some reason it installs not QT version, but it is ok now and mouse wheel is back, thanks.
But I noticed one strange issue in python and vex, while coding it flickers, carret jumps from left to right, sometimes it does that sometimes not, freezes time to time, any ideas what it might be?
P.S. Same happens when renaming nodes

Just adding in to the conversation, I am having a lot of freezing/hanging in Houdini on Wayland, I am working with ocean and for every update even with nodes with display flag off its taking forever to update I had to went back to X11.
I have zero issues with wayland on cachyos... just a bit of mouse wheel but I'm using cintiq so not using mouse and wheel anyway...
I've recently started just started using Linux, specifically CachyOS with KDE Plasma, default everything. I'm stunned that Houdini installed and began running without a hitch but I'm suffering from some of the issues mentioned above, including:
Because of these I can't quite use Houdini on this Linux build for daily use, but it's looking like these will be fixed soon enough. I'm really excited because Houdini on Linux seems to run much smoother than on Windows.
- Mouse wheel doesn't work (except when directly over scroll bar)
- Tab/context menus, at some point during the session, start freezing, making the whole program unresponsive for an indeterminate period of time.
Because of these I can't quite use Houdini on this Linux build for daily use, but it's looking like these will be fixed soon enough. I'm really excited because Houdini on Linux seems to run much smoother than on Windows.
I am on Fedora and it seems that the issues described above are kind the same except the mouse/wheel where it is fixed on my end when I installed the qt5 version.
On X11 Houdini is working normally so I never have to go to Windows thankfully!
