para tentar resolver o problema vou começar por desativar a função de gestão de energia hybrid-sleep.target:
sudo systemctl mask hybrid-sleep.target

Configuring Automounting

To enable or disable automount open a terminal and type dconf-editor followed by the [Enter] key.

Browse to org.gnome.desktop.media-handling.

The automount key controls whether to automatically mount media. If set to true, then Nautilus will automatically mount media such as user-visible hard disks and removable media on start-up and media insertion.

There is another key org.gnome.desktop.media-handling.automount-open. This controls whether to automatically open a folder for automounted media.
