Yes, I adjusted the mouse preferences first. The sensitivity is all the way down. I don't feel that did anything.

Hello, I'm on a Lenovo Thinkpad. My mouse is way too jittery. For example, if I just place my finger on my trackpad without moving it, the mouse will wiggle around quite a bit on the screen. It's also hard to be precise with this hypersensitive mouse, which makes clicking on the edge of a window to resize it difficult.

Uhm, I'm not too sure what other info to provide. I have a "SynPS/2 Synaptics Touchpad," I think. That's what my friend told me. He typed "xinput list" into the terminal.
