Com o teclado Logitech K290 via USB, as teclas F. não são acessíveis por padrão, e eu preciso pressionar Fn antes de usá-las, o que não é realmente utilizável.
A chave Fn sozinha não dispara nenhum evento em xev
.
Pressionar F1 sem Fn dispara dois eventos chave, código 50 ( Shift_L
) e código chave 133 ( Super_L
) e exibe a mensagem "Touchpad desativado" no meu Kubuntu (a mesma mensagem para todas as chaves F1 através de F4 )
Embora a maioria das teclas de mídia funcionem, prefiro ter acesso direto a chaves F. Você conhece alguma maneira de alternar o comportamento Fn ?
Aqui está a saída para quando eu pressionar F1 sem Fn :
