How to run a Jupyter notebook on background ?

As I get disconnected from HLRN roughly every 20 min I can't leave a code running for a while using the ./run_chromium_through_ssh_tunnel.sh script.

The disconnection problem occurs whether I use the Wifi or the LAN.

This is why I am wondering if it is possible to start a Jupyter notebook on a screen on HLRN in order to leave a script running for a long time.

I tried to launch my notebook converted into a .py file on a screen on HLRN :
python campo_bootstrap.py I get the error : segmentation fault

If you have any idea or solution I would be grateful.
