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??
