Sou bastante novo no Ubuntu e agora tenho um problema preocupante.
Após o boot tudo funciona bem. Mas depois de um certo tempo, o touchpad não funciona mais. Apenas um reinício está ajudando. É muito chato -.-
Um mouse USB está sempre funcionando, é apenas o touchpad.
Eu adicionei o seguinte código a ser executado após o início: syndaemon -i 1 -K -d
porque a opção "Desativar toque durante a digitação" não está nas configurações.
Meu laptop é um HP355 (Ubuntu 16.04LTS).
