I notice that sometimes when I wake my computer up from standby, or even booting it up,the cursor jumps to the left over and over. I go to move the mouse, in a second it will be back over to the top-left.

I can temporaily fix the issue by disabling touchscreen input by running xinput disable 9. I even created a keyboard shortcut. However, I want to be able to utilize the touch screen if possible.

I don't think this is a hardware issue because this never occurs mid-usage. Only upon wake, and sometimes upon boot. This issue did not occur when I had Windows 7 or Windows 10 on it. This started occuring a couple weeks after I installed Ubuntu 16.04 LTS.

I have never experienced this until today. Before the sleep cycle I had been experimenting with acceleration using xset m _ _

Sleeping the machine again with sudo pm-suspend and re-awakening it did not help.

What did solve it for me was unplugging and replugging the USB mouse!
