Sou novo no xubuntu (só porque meu laptop não roda nenhum sabor moderno do linux). [pentium m] Aleatoriamente gostaria de obter um teclado desligar - sem aviso prévio. (quando eu digo isso, um par de vezes o menu também não funcionou) O mouse ainda funciona e se eu mudar para outro tty, o teclado funciona bem. daqui eu posso rodar um init 6 para reiniciar o sistema e tudo está bem novamente.
Tenho notado que é mais provável que aconteça quando uso os atalhos de teclado do meu laptop, por exemplo, fn + vol up ou fn + vol down.
Eu não instalei drivers de drivers proprietários nem modifiquei os keymappings. atualizado ou não atualizado, faz a coisa da dama. (Eu já instalei 12 vezes)
em anexo é o meu hardinfo:

Já tive alguns problemas com um laptop Centrino M semelhante:
Pareceu-me que estas funções foram programadas no BIOS e apenas testadas com o Windows. A solução alternativa no momento era anexar a linha de comando do kernel com NOAPIC NOLAPIC, ymmv.
