Houdini Linux Wayland Support? Aug. 12, 2026, 8:39 a.m.

I haven't had any unusual crashes etc. since switching from Linux Mint / X11 to Tuxedo OS / Wayland.

The only annoying thing I noticed (and that I'd like to know if anyone here can reproduce) is that as soon as I use the mouse wheel over a Parameter Editor all of its contents disappear and are gone for this session of Houdini.
What I mean is:
  • Open Houdini
  • Add a cube
  • Hover the mouse pointer over the Parameter Editor (where you set Transform, Render and Misc)
  • Use the mouse wheel -> Everything inside the Parameter Editor is gone and does not come back.

Apart from that it has been a great experience so far.

EDIT: Quick update: Today I switched the nVidia drivers to "tuxedo-nvidia-driver-580-open" (Driver Version: 580.178.04) and the beforementioned problems are gone now.

Something went wrong connecting to hserver: Could not connec June 6, 2026, 12:12 p.m.

I had this problem on 3 different systems now. 1 Linux and 2 Windows.
What helped instantly in all cases was clicking the "Logout" link in the displayed browser window and then directly logging in there again.

Like I described here: https://www.sidefx.com/forum/topic/83318/#post-460494 [www.sidefx.com]

Houdini Launcher stuck in "log-in" loop? June 4, 2026, 5:48 a.m.

Today I got bitten by this again.

In my case the fix was to click on "Logout" on the web page that opens when clicking "Log In" in the Launcher.



After that I logged in in the Browser again and all of a sudden the Launcher worked again.
