I agree that good software should do this but unfortunately multi-monitor configuration software isn&#x27;t always very good. My Ubuntu 15.10 system with Unity desktop decides to move the taskbar&#x2F;dock thing to the other monitor every time I turn the other monitor on in the morning. There is nothing in the Screen Display GUI that seems to allow me to stop this from happening. Out of frustration I&#x27;ve resorted to running the xrandr command a few times (once is sometimes not enough!) to fix it each time. This tool would at least automate the task for me and seems useful.
