Unable to launch paraview: Could not load the Qt platform plugin

ParaView Support
1

Hi,

I am trying to install ParaView-5.9.1-MPI-Linux-Python3.8-64bit on Ubuntu 20.04 LTS on a Windows10 machine. When I enter ./paraview in the bin directory, it returns:

qt.qpa.xcb: could not connect to display
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: xcb.

error: exception occurred: Child aborted

Can you tell me how to fix it?

WSL is not supported, use the windows release downloaded from:

https://www.paraview.org/download/

But the windows release would become like this when I loaded an exodus file

Intel bug, see here for solutions:

You need to install the xcb libraries (should be libxcb-x11 in Ubuntu).

On Ubuntu 22.04 it’s libxcb-xinput-dev

On my Ubuntu 22.04, my error message is a little different

$ ./paraview
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway.
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: xcb.

error: exception occurred: Subprocess aborted

FYI, my box does not have any GPU graphics card.

The Qt client requires a graphical environnement.

Best,
