Comment 161 for bug 1566302

For anyone dealing with this issue on a Dell XPS 13 with a touchscreen on Ubuntu 16.04, it seems to re-enabling the touch screen in the laptop bios resolved it for me. I usually keep the touch screen disabled but there must have been a regression in one of the kernel updates that I got that made it suddenly an issue.

I'll update this comment if it turns out I was just lucky for the last few days and that isn't really the solution.
