I'm trying to find the control panel that will let me configure various things about my touch pad such as disabling it when other devices are active and what not. I keep accidentally touching my touchpad while I am typing which causes the cursor to jump somewhere else and then text goes there until I realize what happens and have to try to undo it. I want to be able to have the touchpad ignored when I am using the trackpoint on my computer somehow. The only setting I can find at all related to my touchpad is Preferences -> Keyboard and Mouse, but it is very minimal and doesn't even touch on the touch pad.
In my research I found that there is a package called "gsynaptics" that I need to install after which I should run gpointing-device-settings. However, when I try to install it, it says the package is not found, and when I try to run gpointing-device-settings it doesn't suggest any repositories I could find it in. I have also noticed that most questions about this topic are several years old and in one place it suggested that gsynaptics is no longer used (but then they went on to indicate that they had, in fact, installed it, without saying how).
From what I have read, this package was in Universe, but under "Software and Updates" the "universe" setting is already checked.
Where can I find the package to let me configure my touch pad in LUbuntu 18.04 in this way?
