Bug Description

I just plugged in an external monitor to my X301 and Xmir ?? appeared to crash and then restart with the external correctly recognised. I was able to use displays to change the location of the external and launcher placement and am typing this message now using the configuration. I had to log back into Ubuntu and restart my apps after plugging in the external.

Also, unplugging the external worked fine - reconfigured to laptop display only with no problem.
