Slow Cursor Movement on the Touchpad When Using an External Monitor
I use Arch Linux. When I connect an external monitor to my ThinkPad, the cursor moves erratically on the touchpad. It moves slowly, stutters, doesn’t go where I want it to, or goes past the target. There’s no problem with the mouse. The touchpad doesn’t always cause problems—it happens sometimes, and it’s very frustrating.

do you have both monitors on at the same time? if so it would be worth checking if the problem also occurs if you have only the external display on.

What DE/WM do you use? Have you tried replicating the problem on a different one?

I’ve had this happen, I swear it was a ground problem. Does it behave the same if you are plugged into power? Also, is the mouse connected when it’s happening?
