Touch-pad dosen't work after installing Ubuntu 14.04 [Dual boot with Windows 8]

Asked by erkanp on 2014-10-01

I just bought a new Acer Aspire V 15 Nitro computer with a pre-installed Windows 8. I installed Ubuntu so I can run dual-boot. Everything works fine now except my touch-pad that isn't working in Ubuntu but works fine when i boot into Windows. And when i'm in Ubuntu my USB mouse works fine aswell.

 cat /proc/bus/input/devices

 cat /proc/bus/input/devices
This command does not show any SynPS/2 or anything.

When i run

    xinput --list
Under the Virtual core pointer there is only one

    Virtual core XTEST pointer
    Logitec USB-PS/2 Optical Mouse
and then there is a empty slot where I think my touch-pad should be.

In my system settings I can see the touch-pad and turn it on/off but nothing happens. I also installed Touch-pad indicator but nothing happens aswell.

When I run

    cat /var/log/Xorg.0.log | grep -i synaptics

    [ 4.362] (**) : Applying InputClass "enable synaptics SHMConfig"
    [ 4.362] (II) LoadModule: "synaptics"

    [ 4.404] (--) synaptics: : touchpad found

After running

     grep -i touchpad /var/log/Xorg.0.log
the output is

      [ 4.362] (**) : Applying InputClass "evdev touchpad catchall"
      [ 4.362] (**) : Applying InputClass "touchpad catchall"

but when i run

      xinput -list

there is nothing with id 12

Hello Cyhex I have not personally solved the problem yet but our friend Kai who had the same problem did solve it. Kai replied to me: I solved the issue on my machine by updating the kernel to 3.16.0-031600-generic. Works like a charm now.

Hope that helps
