Estou tentando alterar as fontes no meu sistema Ubuntu 18.04 usando gnome-tweak-tool e sempre que vou para a guia de fontes e tento clicar em qualquer um dos menus de seleção de fonte, o programa irá travar e desconectar-me automaticamente.
Eu tentei registrá-lo, mas eu literalmente não posso desde que ele me desconecte. Não sei qual é o problema, mas se houver alguma indicação do que está errado, quando instalei gnome-tweak-tool , não tinha a pasta .themes e tive que criá-la manualmente.
Eu fiz $ sudo apt remove gnome-tweaks , o que remove gnome-tweaks e gnome-tweak-tool , seguido por $ sudo apt install gnome-tweak-tool como um esforço para reinstalar o pacote. Relançar novamente deu exatamente o mesmo problema.
A saída de $ gnome-tweaks --version é 3.28.1 e a saída de
$ uname -a dá:

Para o contexto adicional, eu segui exatamente o mesmo processo de usar o gnome-tweak-tool e consegui mudar as fontes sem precisar me desconectar ou algo do tipo, tanto o meu desktop quanto o laptop que este problema está rodando Ubuntu 18.04
