Enter ‘touchpad’ in the search field in the software installer, and see what happens…I used ‘touchfreeze’ on my previous laptop, but there’s more programs to manage the synaptic touchpads. I’d use one of the KDE ones.
I did such a search but there is very little there - which is why I tried gsynaptics. I was kind of looking for synaptiks which I was using (successfully) with another distro on KDE, but it isn’t there. ‘Package search’ finds many versions of it but I tried a few and got errors about invalid meta-data in the repositories.
The description of touchfreeze is a bit ambiguous - does it do more than just disable on typing?
