What do the numbers mean when fiddling with "Synaptics Palm Dimensions" on Ubuntu?
$ xinput list-props 12 ......... Synaptics Palm Dimensions (296): 5, 5 .........
Can anyone shed any light on this? Many how-tos I've seen say to experiment with them until you find something that works, but even the documentation doesn't say what they actually mean.
Currently on Ubuntu 17.04, if that makes a difference.
