UPDATE: I found my solution lacking in that the right-click tap event from TwoFingerScroll doesn’t always work for all apps (some games – Darkest Dungeon – for example.) See my preferred fix in italics below.
- Two-finger scrolling in Google Chrome is nigh-unusable with Dell’s most recently provided driver. Scrolling works fine in Firefox, IE, Explorer, etc. (as of 16-MAR-2017, the 220.127.116.11 driver)
- tap-to-click doesn’t work with two finger tap for right-click.
Windows 7 x64 (x86 likely the same)
CAUTION: This is going to install some drivers that are not supported for your platform and modify your registry. You do so at your own risk. Also I suggest you have a USB mouse handy to use in case your trackpad stops working during the driver swapping and your windows keyboard navigation skills are 100%.
My new preferred fix:
Use this driver – Synaptics 18.104.22.168 from Dell.
Configure it how you like. two finger tap-to-click is missing from the configuration utility, however, two it works native on this driver with the following registry changes:
- Try searching the registry for other instances of 2FingerTapAction and changing them to 2
- The entry(ies) for MultiFingerTapFlags may need to be changed to 3 if it isn’t already – mine was already set. (credit Amit Toor)
The Old Fix:
You want either:
the ASUS driver
And TwoFingerScroll (credit awahlig) – I find the physical buttons on this trackpad unbearable, so I use touch tapping only, and two-finger touch tapping is not in either of the above drivers (but it is in Dell’s – they did that at least)
I prefer the Synaptics Generic because I installed it second and didn’t notice and significant differences and it is a newer driver. You may need to disable driver signing.
This is quick and dirty, so forgive the lack of exhaustive research, but it worked, and I’m very pleased so I want to share it with the world:
- Download the ASUS driver or the Synaptics Generic Driver (same as above)
- Uninstall any Dell Touchpad Software and/or Synaptics Software in Add/Remove Programs; restart
- Unzip the file you downloaded. Setup.exe will not work because it won’t detect your hardware.
- Go into WinWDF/x64/ and run all the .exe applications there. Some won’t run, some will give you no feedback (yikes) but ultimately I think this is installing the control panel extensions; restart
- Go to the device manager, and manually install drivers located in WinWDF/x64/ (you’ll need to choose “Let me pick, then ‘have disk’ “)
- You’ll now have this in your mouse control panel, and two-finger scrolling will be majestic in Chrome again:
- [BONUS] Add back two-finger tapping for right click with TwoFingerScroll (Oddly enough, we won’t be using the two-finger scroll option, I personally find the latest Synaptics implementation not as configurable, but more responsive.)
[DOUBLE BONUS] you may find these registry keys helpful for speeding up the pointer if its too slow. These ones below are double what I had previously (100 and 40 respectively), much better in my case.
- Try doing both ASUS followed by Synaptics
- Try running the Synaptics Setup.exe after following all the steps, it should let you run it now that you’ve forced an install.
- Try using TwoFingerScroll’s scroll implementation instead of all of this – just note it takes control of all two finger gestures (two finger tap-to-click for example)
