the new contact detection defaults are bad

(atleast for me)

hey, i have a sp5 and this commit kinda borked the touch registration for me. i tought the touchscreen has just started to die, but after looking into it, the new ActivationThreshold and DeactivationThreshold values are just way too high for my device to get consistent touch events. maybe i just have small fingers, or my touchscreen is just less sensitive
im just leaving this here so others can maybe find out what caused their touchscreen to stop working, since i for one did not even know about iptsd having a config file before this, and the calibration article on the wiki doesnt even mention these two values.

ok sorry for bothering, have a nice day :)

I have the same problem on my SP8. Tapping on something is only recognized when tapping hard and swipe gestures are not recognized at all.

Resetting to defaults returns the original behavior.

[Contacts]
ActivationThreshold = 24
DeactivationThreshold = 20
OrientationThresholdMax = 5

EDIT: You need to add this values to your iptsd configuration and restart the service.
e.g. /etc/iptsd.d/90-baddefaults.conf and sudo systemctl restart $(sudo iptsd-find-service)

Thanks! I've been pulling my hair out all week trying to figure out why touch on my SP8 became bad all of a sudden. This fixed it!

Same problem on my SP5, I need to really press my finger on the screen for it to register the touches, especially when doing multitouch gestures like the 3 finger swipes in gnome-shell.
