Ele trava devido a uma falha de segmentação, mesmo que seja uma nova instalação de uma construção estável do GUFW.

Como corrijo o problema?

    

Answer 1

Digite o seguinte comando em um terminal:

echo $XDG_SESSION_TYPE

Se retornar Wayland , digite:

xhost si:localuser:root

para permitir que o root inicie aplicativos gráficos nas sessões do Wayland.

    

Answer 2

Dê uma olhada aqui , eu tive o mesmo problema ao executar o Manjaro KDE. Simplesmente mudando isso, funcionou corretamente:

/etc/sddm.conf
DefaultPath=/usr/local/sbin:/usr/local/bin:/usr/bin

A explicação, no tópico citado.
