Refiz os testes com cada plugin, testei novamente com o Cheese. Os repositórios estão ativados e o Ubuntu está atualizado, uso a versão 14.04. Então, em relação a tecla de atalho (chave), não tem nenhuma dedicada à WebCam, tem de: configurações, brilho, projetor de slides, touchpad, volume e wifi, apenas. E já testei com todas elas, rsrs!
Cara, agradeço pelas orientações, leio e releio cada procedimento pra compreender os comandos. Acho que o problema é esse notebook mesmo olha, rs! Só me tira uma dúvida, será que se eu comprar uma WebCam externa, ela funciona? Tô pra fazer isso!
