[ubuntu] Cursor jumps

I just installed Ubuntu 16.04 on my Inspiron 7568 the other day. For the most part, it works great; flawless. However, I've noticed that the cursor tends to jump a lot when I'm typing email messages, etc. It's quite aoying and the ability to disable the touchpad while typing isn't an option in this version of Ubuntu. I did a Google search and there is an app called Touchpad-Indicator that's capable of doing the same; at least, with older versions. Although the app's still technically available (I was able to go through the motions of installing it from the Terminal) when I try launching it nothing happens. It also hasn't added any new functionality to the 'Mouse and Touchpad' utility. So, now I'm out of ideas. Does anyone know how to fix this?
