Having the same issue on Precision 5520. Started happening after upgrade form 16.04 to 18.04 as well. I don't have Synaptic drivers installed, using libinput.
Running the same kernel as for 16.04, 4.16.18-041618-generic installed from http://kernel.ubuntu.com/~kernel-ppa/mainline/
What kind of logs would you need to help debug this?
