Unsolved qt.qpa.xcb: could not connect to display 172.25.240.1:0

Hi, I am on WSL and trying to use paraFoam on the Ubuntu terminal. I'm new to this stuff and would need help.
With export QT_DEBUG_PLUGINS=1, I have the following result:
Invalid $PV_PLUGIN_PATH and -plugin-path= not defined No supplementary ParaView/OpenFOAM reader modules Using builtin reader: paraFoam -vtk QFactoryLoader::QFactoryLoader() checking directory path "/usr/lib/x86_64-linux-gnu/qt5/plugins/styles" ...

I tried to find a solution on the internet but could not solve the problem.
Thank you very much for your help. -
@tmj4
This should not be a Qt/xcb issue. Try to run, say, anxterm
, it too should say it can't connect to your X display at172.25.240.1:0
. -
This post is deleted! -
@JonB
Yes exactly, by writingxterm
I get:xterm: Xt error: Can't open display: 172.25.240.1:0
What do you suggest? -
@tmj4
I suggest you find out how to correctly address your X display under WSL, about which I know nothing. Nor do I have a clue what "paraFoam on the Ubuntu terminal" might mean or indicate. Is it a remote display for which you need to use that172.25.240.1
IP address, or is it a local display? Check whatever must have set that up as your X display. -
@JonB
It's for a local display.
Thank you very much for your help I will keep looking. -
@tmj4
Last thought ('coz not my area); from a shell:export DISPLAY=:0 # or maybe :0.0 xterm
make any difference?
