My touchpad stop working

[Emiliano Falabrini]

I followed this

In case your Touchpad doesn't work at all (No response from the Touchpad)

This is generally a case of a kernel (linux) or xorg bug.

    Execute at a terminal:

    cat /proc/bus/input/devices

    One should see a touchpad device, like:

    I: Bus=0011 Vendor=0002 Product=0007 Version=01b1
    N: Name="SynPS/2 Synaptics TouchPad"
    P: Phys=isa0060/serio2/input0
    S: Sysfs=/devices/platform/i8042/serio2/input/input8
    U: Uniq=
    H: Handlers=mouse2 event8
    B: EV=b
    B: KEY=420 0 70000 0 0 0 0 0 0 0 0
    B: ABS=11000003

    If you do not find something like this, then the bug is in the linux kernel. Please follow these steps:

        File the bug against the linux package by running ubuntu-bug linux.

        Provide the general information.

        Enter the following commands in a terminal:

        cat /proc/bus/input/devices > ~/devices

        Attach ~/devices as separate attachments to your bug report.

This duplicates bug 1856499, which has also Synpatics TM2985. The root cause is probably still bug 1854798.
