Not sure if it's the same problem but...(I have 2 1080 monitors connected to my docking station and a Envy 4 laptop (core i3) running Linux Mint 20. If I have the laptop open, so effectively 3 screens, then there is no problem. Everything works fine, no mouse lag. However, if I close the laptop lid, then the mouse becomes incredibly laggy on the two 1080 monitors. If I open the laptop again, then it fixes itself. Any ideas?
