I can't get window snapping to work in 16.04 LTS. It has worked previously, and stopped working at some time many months ago. Neither dragging the windows with the mouse, nor the Ctrl-Super-Arrow shortcut work.
Snapping does work on a guest login, so I'm guessing this is some config issue. I've tried deleting my compiz config as per this answer, but no luck. I also tried running
sudo dpkg-reconfigure compiz, but not luck. What else can I do?
This is all running on a Intel Core i5-3317U with integrated graphics and the default drivers.
