touch is constantly jumping around (ghost touching)

[aras]

The issue I am having is very similar to this bug: https://bugs.launchpad.net/ubuntu/+source/xorg/+bug/1574667

Depending on what applications are running the apparently random behavior may increase. Sometimes it is really bad and several times in one second the system detects random touches around the screen. As a result Ubuntu automatically zooms in or out or moves the content of screen around or the focus is stolen. Right now as I am typing this bug I am getting very dizzy because the UI is constantly zooming in and out. I have noticed this happens a lot (A LOT!) more frequently when chrome is opened.

I have tried removing a few xorg input packages as a desperate attempt to stop this:

```
sudo apt-get remove --purge xserver-xorg-input-libinput
sudo apt-get remove --purge xserver-xorg-input-synaptics
sudo apt-get remove --purge xserver-xorg-input-wacom
```

Right now my touch screen is not working and my touchpad never worked.

I have plugged in an external mouse and it works, up until the focus gets stolen from it by random touches around the screen. Before I
removed libinput mouse pointer was also jumping constantly to a random location. But since I remove libinput, mouse cursor stays where it is but random touches seems to be happening anyway.

This is extremely annoying behavious and is rendering my laptop useless.

I am using Acer Spin 5

Help please!

I know for sure now that the touchscreen is the culprit:

↳ Raydium Corporation Raydium Touch System id=10 [slave pointer (2)]

If I disable this device using the command `xinput disable 10` the behavior stops immediately. I will not be able to use the touchscreen anymore, however, the touchpad and mouse work fine. Any ideas how I could debug this further?
