Few weeks ago I changed from Windows to Linux Mint. Now I'm having problem with using multiple displays. When I attach computer to docking station computer starts to be very slow and it does not work as smooth as it worked in Windows. And my laptop diplays has some strange blinking if I take my pointer there.
My sys info:
