Linux: Missing Mouse Pointer? Try This

So on my upgrade from Wheezy to Jessie, I found myself (amongst other issues) looking at a graphical interface where the mouse worked fine, but no mouse pointer was visible. After trying a few other things, it turned out that :-

gsettings set org.gnome.settings-daemon.plugins.cursor active false

Did the trick.

Of course that tip came from somewhere else, but as it worked for me, it’s worth making a note of.
