A câmara Web integrada pára de funcionar quando levo o computador levemente

Question

Quando estou trabalhando com aplicativos que usam webcam (cheese, skype) Ele funciona bem. Mas se eu mover um pouco a tela do meu laptop Ele pára de mostrar. Após a reinicialização do aplicativo, a webcam está funcionando novamente.

Eu tenho o Ubuntu 14.04 LTS 64 e o Lenovo Thinkpad Edge E130.

Aqui está a saída de dmesg depois que eu levemente movi o laptop usando queijo.

O que fazer? Espero que não seja um problema de hardware, já que apenas reiniciar o aplicativo sem nenhuma ação física ajuda um pouco.

    

Answer 1

Este é definitivamente um problema de hardware, já que está dizendo que a câmera foi desconectada e depois reconectada:

usb 3-4: USB disconnect, device number 15
...
usb 3-4: new high-speed USB device number 16 using xhci_hcd 

A câmera é conectada usando um cabo USB interno no laptop, que é de alguma forma solto e, assim, quando você move seu laptop, ele é desconectado rapidamente e depois reconectado, fazendo com que o aplicativo o use para travar. As webcams em geral (e especialmente as laptops embutidas) não são projetadas para serem desconectadas e reconectadas enquanto estão em uso, e as aplicações que as utilizam (queijo) não são escritas para suportar isso.

Não há como consertar isso com qualquer alteração de software - você precisa abrir o laptop e conectar-se corretamente ou substituir o cabo de fita interno, caso esteja danificado.
