Eu tenho um Dell Precision 7510, executando o Ubuntu 14.04.5 LTS. Eu instalei recentemente os pacotes de kernel mais recentes (4.4.0-57-generic), e quando o fiz, parece que meu mouse de laptop foi detectado de forma diferente (costumava ser um genérico PS / 2).
Meu TouchPad parece estar ok, mas o Stick agora atua com uma sensibilidade / aceleração extremamente alta a ponto de ficar inutilizável, e não posso abaixá-lo. Eu o criei (usando as configurações do mouse do xfce, sob o dispositivo Stick), e quando o fiz, o mouse literalmente vai de um canto da tela para o outro instantaneamente.
Eu tentei os seguintes comandos, que resultaram em alteração zero:
xset m 0 0
xset m 1/10 0
xset m 1/1000 0
Consegui usar o xinput para modificar a sensibilidade do TouchPad, alterando o "Synaptics Finger", mas foi complicado. Está bem o suficiente, então estou deixando isso em paz. O verdadeiro problema é o pau; que eu não posso mudar através de qualquer propriedade. Veja abaixo:

Eu mexi com todas as propriedades do Device Accel, novamente, sem sucesso.
Agradecemos antecipadamente por qualquer ideia !!! Isso está me enlouquecendo, e eu posso ter que ficar em um antigo kernel 3.x.
