Does it stutter, or is it just the sensitivity that appears very low?
You can try this solution if it's just insensitive.
xinput --list --short and see if you can locate your mouse.
For example, my mouse listed looks like this:
SteelSeries World of Warcraft MMO Gaming Mouse id=8 [slave pointer (2)]
If your mouse is listed, you can try this:
xinput --set-prop "Your mouse name" "Device Accel Constant Deceleration" X
and replace X with an integer somewhere between 1 and 10, where 1 is very insensitive.
For example, like you can see, I have the the MMO mouse from Steelseries. My command would look like this (my problem is, unlike yours, that the mouse is too sensitive)
xinput --set-prop "SteelSeries World of Warcraft MMO Gaming Mouse" "Device Accel Constant Deceleration" 3
If this doesn't work, you can try replace the name with the id. If you notice changes, but it's slower or way too fast, you can experiment with different numbers. Like I mentioned above, the higher the number, the more sensitive your mouse becomes.
Hope this helps!
