Dell XPS 13 touchpad-small movement causes curser back snapping/jumping

Hello,
my problem seems to be known since a while but I haven´t found a solution yet. Here you can see a nice gif which shows the cursor jumping problem:
http://h30434.www3.hp.com/t5/Notebo...ynaptics-Touchpad-snapping-issue/td-p/5395476
I´m running win 10 on my Dell XPS 13 9350. I substituted the pre-installed touchpad drivers (from 2006!) because there wasn't any possibility to use any gestures at all (2-finger scroll etc.).
I tried every synaptics driver for win10 I've found so far and used this tutorial:
http://forum.notebookreview.com/thr...hpad-ptp-driver-with-synaptics-driver.783990/

NOTHING works for me. Does anyone solved the problem so far? Please let me know

 

Simple answers no as you have already found out!

 

No kidding, but I solved the problem now. I just tried an older synaptics driver for Win8. Sounds stupid but now it works like it should.
The version 16.2.12.17 from 2012 works for me after deactivating the palm recognition. The cursor does not snap back anymore as well as the three finger scrolling works. Finally...
Thanks

 

I've never seen this jumping problem on my 9350 with the default Windows precision touchpad driver. I haven't installed any Synaptics ones. I don't understand why you say the "pre-installed touchpad drivers" don't allow gestures.

 

Hey,
I mean the multiple finger moves, for example 2-finger scroll. The stock drivers from 2006 don't allow that on me xps.

 

Then there's something wrong with your setup. The stock driver does of course include two finger scrolling.

 

Sorry for necro-bumping, but this is exactly the bug I'm facing, eventhough I got the M3800 (2013). Actually, it isn't a bug, it's a "feature". Some sort of erroneous click prevention. Most users probably don't notice it or simply don't care, but if certain, unadjustable conditions are met, your cursor's position will be reset. Also, it isn't limited to M3800 / 9350 / Dell, but also happens on other manufacturers' laptops aswell.

Unfortunately, installing the older driver didn't help in my case, nor did installing any other driver version (both, generic and OEM driver). Also, I couldn't find and hidden configuration values in the driver GUI / registry for this behaviour, eventhough there are plenty of settings for fine-tuning. Looks like this "feature" is hardcoded into the driver. I've already contacted Synaptics and they don't seem to be interested in fixing this (or make it atleast adjustable). Still, I think we should be able to fix this, by debugging their software / kernel driver and patching it.

I have some experience in this area, I will try to get it working, eventhough I can't promise anything. I'd be happy, if anyone with more experience could assist me. My plan so far: fire up WinDbg, monitor Synaptics driver, trigger cursor snap-back, identify triggered function which leads to this bug, patch it away and resign driver.

Also, if for some reason this shouldn't work out as intended, CoolStar got an excellent open source touchpad driver for Chromebooks (Synaptics I2C), which we can surely port to make it work with our touchpads.

 

I'm struggling with the exact same problem on my brand new Hp Spectre. It's driving me nuts. Any progress?

 

I've just bought the HP Spectre x360 and have also been having this snapback problem. It uses the Synaptics Driver as well.

Any tiny initial movements are arbitrarily ignored.
