Random cursor movement under multiple drivers, but not in windows
by r1ntse from LinuxQuestions.org on (#522MB)
Every now and then, at random, my cursor moves a tiny bit. This is preventing my laptop from going to sleep, and is just rather annoying anyway. The strange thing is that it doesn't happen in Windows on the same machine.
I am running Ubuntu 18.04 on a dell latitude E5480. I am running the synaptics drivers, but the problem also persists when using libinput.
All while using the libinput driver:
I have determined the xinput id of the device and afterwards located the Device node.
I looked at the events of this node using evtest, and curiously, no inputs are reported when the cursor moves on its own (inputs are listed when I move it myself).
I have no idea where to look for a solution since google page 4+ usually doesn't help very much anymore.
