A few days ago I had my laptop connected to an auxiliary monitor. This had the (unintended) effect of putting the “Configure display settings” icon into my “notification area”. I would like to get rid of this icon and cannot find a way to do so.
I tried removing the whole notification area and then restoring it (using “Add to panel”). However the restored notification area persisted in displaying the “Configure display settings” icon.
How can I get rid of the damned thing? Is there a file somewhere that I can edit to achieve the desired result?
I am using Mate 1.12.1 under Ubuntu 16.04.
