Dell Inspiron 7347 - Cursor inativo com meu touchpad no UBUNTU 14.04

Question

Depois de instalar o Ubuntu 14.04, meu touchpad ficou inativo. Tudo funciona bem no Windows 8, mas no Ubuntu ele não responde.

Eu tentei o seguinte comando, mas o problema persiste: (.

synclient touchpadOff=0

sudo apt-get update

- (isso funciona bem)

sudo apt-get install wget gdebi wget http://http.us.debian.org/debian/pool/main/s/synaptiks/kde-config-touchpad_0.8.1-2_all.deb  

- ((isso não funciona- não foi possível encontrar o pacote por regex ...))

Qualquer ajuda é apreciada.

Obrigado pela ajuda útil. Problema resolvido! :)

    

Answer 1

Você pode corrigir desta forma:

1. Executar

sudo -H gedit /etc/default/grub

Na linha de edição da janela aberta

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

deve parecer assim

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nopnp"

Salvar arquivo e executar

sudo update-grub

2. Executar

   echo "blacklist i2c_hid" | sudo tee /etc/modprobe.d/i2c-hid.conf
   sudo depmod -a
   sudo update-initramfs -u
   echo "synaptics_i2c" | sudo tee -a /etc/modules
   

3. Reinicie.

Por favor tenha cuidado, não digite novamente estes comandos, mas copie-os e cole no terminal, ou você pode quebrar o sistema inteiro, se digitar errado.

Esta solução desativa o Plug & amp; Jogue por i8042 devices e, em seguida, desative i2c-hid module e ative synaptics_i2c em seu lugar.

Plug & amp; Play aciona um módulo errado para este dispositivo.
