When using a Windows laptop, you might be stuck with a synaptic touchpad.

Those crappy drivers with their so-called virtual scrolling create a fake window below the cursor to display their custom scrolling icon.

That window interfere with the signal sent to the application under, and GTK for some reason can't detect that (most likely the devs don't care about us).

The result is being unable to scroll in popular GTK apps like Wireshark or Pidgin.

After playing with Spy++ and Procmon for some time, I found an interesting registry key that solved my problem.

This setting will disable the custom cursor when you scroll, effectively fixing the scrolling problem in GTK apps.

First you have to open regedit. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Synaptics\SynTPEnh and create a new DWORD called UseScrollCursor with a value of 0.

Restart SynTPEh (or reboot).

Scrolling should work in GTK apps now, but you won't see the scrolling cursor anymore.

Update: If that does not work, you can try to run

taskkill /im SynTPEnh.exe

This didn't fix the problem for me on Synaptics driver version 15.3.6.0.
After some searching though, I found http://forums.mozillazine.org/viewtopic.php?f=38&t=1524405
Which works wonderfully :)

Excellent!

Just started using Geany after a recommendation and my only bugbear was the loss of scrolling on my touchpad. Now it's back!

This worked for me on a Toshiba L505. I had tried different drivers, but this worked with the original drivers. Thanks for this.

Wow, I don't even know what to say but a really big thanks! I have been looking for the answer to this for awhile, and it works perfect! No more stupid mini scroll bar and all my programs scroll with 2 finger. BTW I did this on and HP Envy 14.5(Second Gen).

I thought this was a firefox related problem until I realized that evince was also having the same issue, it took me a while to add up that it was a gtk thing.

Thanks.

Thank you so much! Finally I can zoom in Rhino (cad software) and scroll in Steam!

This method works for scrolling with Steam, but I'm having a problem when clicking on windows on the Community Hub, specifically Videos. I click on one, exit out, then click on another window, then the entire page freezes. I'd have to hit the back button several times or refresh the page. Anybody else having this issue?

Worked like a charm, thank you for taking the time out to write that up. +1UP mushroom for you!

3 years of using laptop and didn't thought to find way to fix it. My life will become so much easier.

I made it all the way to the DWORD step. I got lost from that point on. Please explain in simpleton form. I am computer and electronically challenged. Thanks.
avatar
OK, I found out how to add the DWORD thing. The DWORD is for 32 bit systems. The fix didn't work for me. My system is a 64 bit. I had the option of using a DWORD or a QWORD, which is for 64 bit systems. Should I try the QWORD and use the same instructions? Thanks.

thank you so much for this, but how do I autorun the taskkill thing?
