o girador no nautilus deve ser do gtk3, vc pode configurá-lo no seu arquivo gtk3 de temas atuais, para mim seu /usr/share/themes/KILLMINT/gtk-3.0/gtk-widgets.css
abre ele e procura pela string spinner
você vai encontrar algo parecido com isso spinner
/***********
* spinner *
***********/
.menu.spinner,
.primary-toolbar .spinner,
.primary-toolbar .spinner {
color: @theme_selected_bg_color;
}
.spinner:active {
transition: 750ms linear loop;
}
e tente olhar para outros temas ou distros como é o seu spinner e pegar o código dele (+ verificar qual engine ele usa como engine = none; ou engine = unico; e se são algumas funções daquele engine usado em código do spinner)
tente o código do spinner da zorin:
/***********
* spinner *
***********/

isso fará com que seu spinner pareça feito de círculos, eu colocaria uma captura de tela, mas não tenho alguns pontos (eu também os adiciono) no entanto spinner gtk2 vai reamin o mesmo que eu não encontrei como configurá-lo, parece hard-coded em algum lugar, mas o seu nautilus vai usar aqueles de gtk3 como o meu nemo faz, por isso não deve ser tão ruim ..: D aplausos KiLLA
