-- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to xorg in Ubuntu. https://bugs.launchpad.net/bugs/1667133 Title: touch is constantly jumping around (ghost touching) Status in xorg package in Ubuntu: Expired Bug description: 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 ``` $ lsusb Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 007: ID 0bda:0129 Realtek Semiconductor Corp.
