Parece que o dispositivo está ativado, o driver xinput carregado, mas não funciona. Não foi possível obter nenhum evento no dispositivo. Alguma idéia?
Primeiro, verifique se cat /dev/input/event11 e a tela tocante fornecerão alguns dados no terminal. No caso, o dispositivo e o driver do kernel funcionam corretamente.
Outra coisa, verifique se o seu usuário está no grupo "input". Para mim tudo, exceto TS funcionou bem, mesmo sem o meu usuário estar no grupo de entrada.
