I use two external screens with DisplayLink.Every time when I start Ubuntu, lagging box occurred in both screens.
As the problem describes as: Lagging box around mouse cursor on Ubuntu 17.04 and nvidia driverr



So restarting lightdm service will solve the problem.



But it is really annoying to restart lightdm service wiht terminal everytime.



Can someone please teach me how to solve this ?
