Some information about my issue
I just installed 17.10 on my laptop. the installation process went fine, and additionally I was running a live USB in order to test if everything functioned. One thing I noted myself, was that whilst moving the mouse, the mouse felt like taking steps in every direction - resulting in a laggy movement.
If you have a grid, it feels like the mouse is attaching itself to every cross in the grid, whilst moving. The effect is mostly noticeable in diagonal directions, but can also be noticed elsewhere. Doing smaller movements is challenging, as the mouse bumps.
I tried changing the available settings in the stock settings menu on the system, without any apparent luck. I also tried searching for similar issues, but I am not sure if they describe my problem exactly. For instance, lets have a look at: Jerky mouse movements

I've tried changing a few values here, but had no luck as of yet getting rid of the "grid movement" of my track-pad.
Connecting an external mouse to the laptop seem to come around the issue, but I am still not satisfied with the performance of the track-pad. Moving the pointr with my track-pad is not going well.
If there is any other information that would be handy to have, just let me know and I'll provide it. It's an annoying issue as I can't use my external mouse at all times.
