Re: Thinkpad X1 Carbon 2017 Gen5 Touchpad Issue

I also am finding that Disabling Edge tap filtering instantly corrected the problem. I do think we need to give it some time to see if it flakes out, just like rebooting the computer eventually flakes out.

Also, like Frogybloop, I didn't find that setting the tap to no delay helped. Only the Edge tap filter.

Lastly, though I'm not sure I consider disabling a feature to be an acceptable fix - I haven't noticed any disadvantage to having it off. Wonder if that was even in the prior driver.

Re: Thinkpad X1 Carbon 2017 Gen5 Touchpad Issue

After I reboot the Windows, I found the trackpoint scrolling had a problem. The problem is that cursor moves along when I scroll with clicking the middle button(Set to scroll). and still trackpad has no problem after changing Edge tap filtering to disabled

After another reboot, the trackpoint also works fine. It is weird... Smiley Sad

Re: Thinkpad X1 Carbon 2017 Gen5 Touchpad Issue

So it's the next day and I'm very happy with my machine. The touchpad seems to be working perfectly now. To be honest, that "edge tap filtering" is such a specific setting I'm not sure how noticeable it's function would be either way, so while I agree it still a workaround, I'm feeling I can now relax that at least it's not a hardware issue that requires the hassle of repair or replacement.

 

It would be in everybody's interest for Lenovo to update the drivers ASAP.

About a day. It certainly has something to do with egde filtering.

Would be very nice of Lenovo|Synaptics to fix the firmware.

This is really disappointing for such an expensive device.

I don't know a way to disable this broken feature on linux.

Re: Thinkpad X1 Carbon 2017 Gen5 Touchpad Issue

Thanks for reporting the possible fix. Certainly keep us updated on if it continues to function properly.

 

In other news, because I had already ordered a replacement before we found the "edge tap filtering" solution, I decided to still let it ship since Im curious to see if this separate machine might not have the same issue. It should be here tomorrow so I'll test it then and post here if I can recreate the issue there as well.

Re: Thinkpad X1 Carbon 2017 Gen5 Touchpad Issue

It reappeared some minutes ago.

I am really unhappy with this way too expensive, not-properly-working device. Smiley Sad
