see commit 342bc510164e89d7c9a742406fb98f9deabf5c8f and e.g. bug 93583. Your device is a semi-mt device and we disable gestures on them by default because the data we get is largely garbage. I'll have a more detailed look at your recording later but right now all I can say is this is, unfortunately, intended behaviour I hope this will be fixed soon, I think a large part of laptops are equiped with such touchpads unfortunately ! you can try reverting that commit and testing libinput to see how reliable the various gestures are with it. If it works, it may be possible to put a device-specific quirk in for your device needinfo for several months, closing. please re-open when the requested information is available. Hello Peter, I'm having the same problem. Everything is working fine in windows, in Antergos with libinput 1.7.0 only two finger scrolling. With my last notebook (elantech) it was exactly the opposite way :D I've read all the bug reports regarding this problem but i wasn't able to find out which additional information is needed. Could you please tell me how i could contribute to solve the problem? A lot of the new Notebooks are using "Windows precision touch pads" so i guess we'll see a lot more of those semi-mt touch pads... BR, Stefan windows precision touchpads aren't semi-mt IIRC. semi-mt is mostly the opposite of "precision" :) I'll need an evemu-record of your touchpad first to check if it's the same issue, thanks. ping? Closing after 3+ months of needinfo |

Created attachment 128173 [details] evemu recording while swiping and piching on the touchpad. Hi, I am running Wayland with gnome-shell 3.22 and Archlinux on my Dell Latitude e7440. Everything is up to date, including Bios. I also checked that I'm using libinput driver for my AlpsPS/2 dualpoint touchpad (libinput-list-devices --version: 1.5.0). However, swipe (3 or 4 fingers) and pinch events seem to be interpreted as two-finger gestures: using `libinput-debug-events`, only "POINTER_AXIS" events are reported while swiping or pinching with 2, 3 or 4 fingers. When I boot on the Windows partition, 3 finger swipes are correctly interpeted, so I know the touchpad is technically able to handle such gestures.
