I’m running up to date 16.04. I have 2 user accounts on a docked Dell 4310 with external monitor. When switching between accounts I am experiencing multiple issues. Most recently the mouse pointer disappears. I found an old forum that says launching a terminal CTR+ALT+T and typing ls works. It does work for me. Very inconvenient espeically for the wife. Also recently switching users messes with the multi monitor set up. Any one out there with similar issues? No mouse pointer sucks. Thanks
