remove tap timeout

[Nicolò Chieffo]

Binary package hint: xserver-xorg-input-synaptics

Currently in the driver there's a strange option to lag 180 milliseconds before executing a tap.
I find the option useless because it feels that my desktop isn't responsive.

The option name is SingleTapTimeout

while it's definitely true that single taps feel more responsive with a lower timeout I have noticed that double taps are much more difficult to perform, for example when I double tap and drag my finger to select some text.

Furthermore touchpads may have different sensitivity. This looks to me more like something which every user should be able to customise according to the sensitivity of their touchpad.

If other users are affected by this problem, they can try with:
xinput set-int-prop $YOUR_DEVICE "Synaptics Tap Durations" 32 180 180 100

and change the first "180" with a lower value.

I'm marking this as incomplete, because I didn't understand your opinion.

If you only want to make double taps easier you don't have to change the value of SingleTapTimeout (as the name also suggests). you can change the value in the mouse configuration named "double click timeout" which is definitely not affected by SingleTapTimeout

[Alberto Milone (albertomilone)]

I know what "double click timeout" is. My objection was that SingleTapTimeout seems to affect dragging too (not double clicking).

Feel free to file a bug report upstream and to discuss the current behaviour with upstream here:
