Thank you very much for your reply.

Today I tried some time more, so I would like to avoid installing other things on the server so I went with two moethods, one is trying to use jupyter notebooks, like specified here: [Using MNE with 3D visualization on a headless server - 💬 Support & Discussions - MNE Forum](https://mne.discourse.group/t/using-mne-with-3d-visualization-on-a-headless-server/4917/4) which kled me here: [Little tour of MNE features with the ipyvtk backend (github.com)](https://gist.github.com/GuillaumeFavelier/b470330fa71cfdef4c7be94b966ef49b). I adjusted my code according to what is described in this file (added these imports)

```python
import mne
from mne.io import read_raw_egi
from pathlib import Path

%matplotlib inline
mne.viz.set_3d_backend('notebook') # set the 3d backend

```

And performed the required steps to connect.

With this it simpy crashes, the last line printed is: `Using qt as 2D backend.`

The log is:

```python

}

```

The other method is using X- forwarding. With theis method I keep getting the same error described in the post.

Would it be possible for you to elaborate on how I can connect to it using the -X option when using ssh? Or do you have any Idea on why the jupyter kernel crashes?

Thank you very much in advance,
