Ok that didn't work however I found this   This inverted the scrolling direction, so I also edited the entry for MatchIsTouchpad in /usr/share/X11/xorg.conf.d/90-libinput.conf:   So i'm now testing this configuration. I'll update once i've tested it thoroughly. Wish me luck.   EDIT: This SEEMS to work guys. I'm going to accept this as the solution and keep the laptop. I will write back if issue re-occurs. And finally, I just think I should link to this - this will help you use the 'super' key, to press once and get the search box and hold the super key (aka the windows key on windows) to display a list of useful shortcuts. So on Ubuntu 16.04 LTS, open a terminal and run this:   I think i've finally got my laptop running as it should. Shame it didn't come out of the box like this, but hey, if it's now working, i'm happy.
I've just received my Dell XPS 13 running Ubuntu and it was great until I noticed the touchpad mouse jumping. I use my right index finger to scroll with the mouse, then the left index finger to click and the mouse jumps into the bottom left, usually hitting the recycle bin. It's extremely frustrating and unless there's a fix, I may have to send the machine back. It's just not practical to use it whilst this continues. Is there a solution? Thanks   edit: after some google-fu, I found this: If you open the terminal and type in:xinput set-prop "SynPS/2 Synaptics TouchPad" "Device Enabled" 0 this will disable the SynPS/2 Touchpad, and xinput set-prop "SynPS/2 Synaptics TouchPad" "Device Enabled" 1 to re-enable the touchpad.   The issue *may* be caused by 2 touchpad drivers being installed at the same time. If you type in 'xinput' in a terminal and hit enter, and see   DLL075B:01 06CB:76AF Touchpad id=10 [slave pointer (2)]⎜ SynPS/2 Synaptics TouchPad id=14 [slave pointer (2)] Then that may be the issue (according to what i've read). so i've disabled the Synaptics touchpad and i'm monitoring the situation. If it does fix it, then all is well with the world. It looked like a faulty touchpad but i'm hoping it's just a driver issue. Surprised that the laptop had the issue fresh out of the box though...   EDIT 2: Issue still occurring. Extremely disappointed after spending such a large amount of cash. I'm going to have to arrange a return. I cannot use it in this state.
