installation issue MNE COREG -- on ubuntu

Hi, I’m having issues with getting the coregistration properly working. I installed a fresh conda enviroment with mne (installed via mamba; as suggested by the installation manual). However, when running “mne coreg” in the prompt I get a RuntimeError (File “…/anaconda3/envs/mne/lib/python3.10/site-packages/mne/viz/backends/_pyvista.py”, line 1223, in _is_mesa). How can I get the coregistration gui to work?

  • MNE version: 1.3.1
  • operating system: Ubuntu 18.04

Input in prompt: mne coreg
Output:

Using pyvistaqt 3d backend.

Qt: Session management error: None of the authentication protocols specified are supported
