Comment 7 for bug 2062180

In addition to those udev rules there's some GNOME-specific code in the front end that disables auto-mounting, screen blanking, etc via gsettings. https://github.com/canonical/ubuntu-desktop-provision/blob/5a60b958ce86bd74031fb572e54724be4cae5906/packages/ubuntu_provision/lib/src/services/desktop_service.dart

I suspect we'll need something similar for other desktop environments.
