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.


They are as follows:

PalmMinWidth - Minimum finger width at which touch is considered a palm

PalmMinZ - Minimum finger pressure at which touch is considered a palm

Info source: ftp://www.x.org/pub/X11R7.5/doc/man/man4/synaptics.4.html.

  • Thanks, that's still fairly difficult to understand, but if I squint I can now get my head around the concept :) – ticktockhouse Oct 31 '17 at 16:09
