Your freeview settings likely have been saved from a previous session. You can run the following command in the terminal to clear them:
rm ~/.config/Massachusetts\ General\ Hospital/freeview.conf

Just the segmentation fault.

Is that useful?
I just don't get why freeview started like a charm and now gives a seg fault just after having tried to increase the font size by 2,
and why this persists even with a fresh installation...
Cheers,

Hi,
I had sucessfully installed freesurfer 8.2.0 on Ubuntu 24.04 LTS Noble Numbat.
Freeview was running.
I then changed the font size under preferences from 12 to 14.
Since then, I am getting a segmentation fault when I want to run freeview.
I even did
sudo apt purge freesurfer sudo apt install ./freesurfer_ubuntu24-8.2.0_amd64.deb sudo FREESURFER_HOME=/usr/local/freesurfer/8.2.0 bash fs820_updates.sh
for a fresh clean re-installation but am still getting a crash of freeview whenever I am trying to start it.
Any remedy?
Cheers,
Andreas
