xming and paraview

when I type paraview on ubuntu, paraview do not open and I have the following message ‘’‘paraview and xming are not connected.’’’
Could you give me your advice,please?
I appreciate your kind help.

Xming is an X11 display server for Microsoft Windows operating systems, including Windows XP and later.

Are you using Windows somewhere here ?

If you are using “Ubuntu” with WSL on windows to run ParaView.
Do not do that and use our Windows version.
