Eu tenho um usuário cujo teclado ocasionalmente para de funcionar até que o sistema seja reinicializado. Isso é completamente aleatório e acontece de 0 a 7 vezes por dia. Não houve nenhum problema com o mouse, apenas com o teclado.
Detalhes do sistema: Dell Vostro 270S (desktop) com um teclado Dell, Lubuntu 14.04.1 x86 3.13.0-44-genérico.
Coisas que tentei:
- Outro teclado (teclado básico da HP, como visto no dmesg)
- Outra porta USB
- apt upgrade
Eu tentaria PS / 2 em vez de USB, mas não há essa porta no computador.
Aqui está a saída do dmesg (não há problemas de desconexão ou outros problemas no log):

Estou sem ideias. Alguma pista?
