make sure you set the display env var, eg:

`export DISPLAY=:0`

Hi,  
Still getting error ( is there a link or script available, which shows the steps how to use paraview on cluster). Most of the sites I research saying build paraview which is already being build then load which I did and run paraview it should run but in my case I am getting a error shown below.

```
 Created temporary '25lsmeshcylinder.OpenFOAM'
  QXcbConnection: Could not connect to display :0
```

wait, you are tyring to run paraFoam directly on the node ? There is probably no Xorg server running there. You are supposed to run pvserver and connect to it through a ssh tunnel.

See here for more info : [https://www.paraview.org/Wiki/Setting\_up\_a\_ParaView\_Server](https://www.paraview.org/Wiki/Setting_up_a_ParaView_Server)
