I'm running Houdini on a Ubuntu20.04 Server with out GPU (only CPU).
Is this error due to no GPU?

I would say, yes. Without a GPU, your computer no longer meets the hardware requirements to run the software.

Check the Support menu up above to review System Requirements.

Yes,you are right , it can not draw GUI with no GPU.
BUT I have tested it, although the GUI cannot be displayed, the rendering is performed perfectly by controlling the houdini through hython.
