I have this problem on a Dell XPS 15 laptop touchpad running Linux Mint 18.3 based upon Ubuntu 16.04. This actually defaults to libinput, and that's where I first encountered the issue. So I tried synaptic to see if it would go away (it did not), which led me to this bug. So for me it happens with both drivers, it's just worse under synaptic. With libinput, it doesn't jump as far across the screen. But it does jump, under the scenario described in #52 -- you're moving the mouse with one finger to where you want to click, and you click with the other finger. But at that moment the pointer jumps in the direction of the other pointer (for right-handed people clicking with their pointer finger, this is to the bottom left).
Sadly, these are touchpads without dedicated buttons, but being used by users who are used to having and using dedicated buttons. In either case, it's quite frustrating. And it does not occur under windows, so it isn't a hardware-only issue. -- 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/1574667 Title: Mouse pointer occasionally jumps to the bottom-left corner Status in xorg package in Ubuntu: Confirmed Bug description: Sometimes the mouse pointer jumps directly to the bottom-left corner of the screen, which results in opening the trash window when clicking.
