Hi,
Even with FastTaps enabled in /etc/X11/xorg.conf.d/10-synaptics.conf, my touchpad has a latency (~50ms) when I click by touching it. If I click with the touchpad button, then there is no delay.
Is it possible to make it immediate?
I think the delay might be due to the double tap that wait for a response when a one tap occurs, but i might be wrong.
Here's my synaptics.conf :
Section "InputClass"
Identifier "touchpad catchall"
Driver "synaptics"
MatchIsTouchpad "on"
Option "AccelFactor" "0.0400"
Option "MinSpeed" "0.7"
Option "MaxSpeed" "1.3"
Option "FastTaps" "1"
Option "VertScrollDelta" "-111"
Option "HorizScrollDelta" "-111"
Option "HorizTwoFingerScroll" "1"
EndSection
Anyway, thanks for your help!

I haven't messed with touchpad configurations in about 2 years but I have never configured it using xorg. I personally created a shell script with a series of synclient commands that would run automatically at boot. You could also try using one of the synclient GUI programs, as they might reveal something you're not aware of. There's a good 40 or so different attributes you can configure with synaptic touch pads.

Thanks for your answer. I tried Synaptiks (for kde) a few times ago but it only had the FastTaps switch which, i guess does the same as the FastTaps in synclient. I also tried a few configs with synclient but unfortunately never succeeded.

There's a possibility the xorg files are overriding the others. I'd suggest removing it (or back it up anyway).
Do you get this problem from live CDs? It could just be the hardware.

I just booted from a ubuntu live cd (13.04) and you were right, it has the same problem, and it might be a hardware issue . I've got a Sony Vaio svs1312j3ew which is a recent one, and I don't remember how the touchpad was responding on Windows.

Windows would be a good test to see if it is a hardware issue, but supposing Windows does work fine, it could also have a different configuration, or more reliable drivers. There's a lot of factors, but testing Windows would be a start anyway. There are synclient options that mess with delays, I just don't remember them off the top of my head.

Hi, I just tested from a windows installation disc and the tap works just fine. I'll play with the syncient options to see if i can get to something.

Good to know. So yeah at this point it's either synclient settings or a driver problem. Personally, I'd put blame on the settings

Ok, I solved it by adding ClickTime set to 0 and SingleTapTimeout to 0 also. Tap is now instant !
Thanks schmidtbag for your help.

Nice, good to know synclient was the solution. Sorry I couldn't give you a direct answer myself.
