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.

    Might I ask which:

    1. Which Thinkpad? (CPU model and graphics would be helpful)
    2. What resolution and refresh rate of monitor?
    3. What does the trackpoint do during this? I know you said it’s not the mouse, but I’m just curious.

    If it’s a modern-ish Thinkpad (like ~2018 or newer), these problems are weird and I have no advice to offer, but if you’re one of those guys who daily-drives a Core 2 Duo Thinkpad, I’m curious how they do when hooked to a 4K monitor.
