Recently, my mouse cursor has been randomly moving slightly left and right. It happens at random intervals with a different move patterns. I am running Ubuntu 15.10 on a Lenovo ThinkServer. I use a wired mouse. I tried another wired mouse and I have the same problem.
I disconnected the network, checked for viruses(ClamAV) and open network ports (using
sudo netstat -tulpn) to no avail.
Any ideas why this is happening?
