Comment 49 for bug 1769383

I think a lot of my problems were caused by installing Dash to Dock, changing settings, and then removing Dash to Dock. Some of the settings changed in Dash to Dock seem to affect the Ubuntu Dock that Ubuntu reverts to when Dash to Dock is removed. I think running `dconf reset -f /` fixes the problem, but note that this resets every other GNOME configuration you've made!
