Public bug reported:

Installed Ubuntu 16.04 64 bit (also Linux Mint and other Ubuntu 16.04
based distros) on my Dell Inspiron 5555 AMD A10-8700P Radeon R6.

The touchpad sort-of works for a few seconds (pointer moves but cliking
fails) and after a while it hangs completely. The USB mouse works with
no issues though.

I've found following the steps given here
http://askubuntu.com/a/632570/55128 works:

1. Run
    $ sudo -H gedit /etc/default/grub

In the open window edit line

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

it should look this way

    GRUB_CMDLINE_LINUX_DEFAULT="quiet splash i8042.nopnp"

Save file and run

    $ sudo update-grub

2. Run
    $ 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. Reboot.
