Hi there,

We have two systems running Ubuntu 20.4.3 LTS and we're able to launch Houdini 18.5.633 without a problem on both.

I recently installed the latest Google Chrome 96.0.4664.45 on one system, and then Houdini 19.0.383, which then fails on launch with the following error;

"Qt Error: This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem. Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl, xcb. "

The other system, without the Google Chrome install, was able to run H19.0.383 without a hitch.

Even when trying to run 'hkey', there is the following error;

"qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

Available platform plugins are: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl, xcb."

Aborted (core dumped)


I'd not seen anything when googling the error, but just wondered if anyone else had experienced this or knew of a fix. I've emailed support@sidefx.com but no reply yet.

Thanks very much,

Hey there, Just a thought.. could you write rest positions on your points, scale the Z so your radii are the same in both Z and X directions, do your find function then pop the points back to their original positions?
