The kernel in question was 4.11.11-300.fc26.x86_64. Created attachment 133482 [details]
bundle with evemu logs
This should be:
* swipes down with 3 fingers
* swipes up with 3 fingers
* swipes right with 3 fingers
* swipes left with 3 fingers
* pinching
in this order. I am not entirely sure why there are 6 logs :-/
Just looking at the evemu output here:
Output from one of my scripts that tracks per-touch finger motion. +++ and --- are touch down/up, respectively:

last one is an empty recording, that's normal when using --autorestart.
The log ending with :23 (pinching) has some useful data, but it runs into the issue that we bias heavily towards 2fg scrolling on touchpads that only support 2 fingers (of which this is one). Try a 4.12 kernel and see if this touchpad is supported through rmi4 - then we'd get 5 slots and can do better gesture detection.
This was on a Fedora 26 with kernel 4.11.11-300. However, it seems like the situation is still the same with Fedora 26 and kernel 4.12.8-300. Aha: [ 2.099538] psmouse serio1: synaptics: Your touchpad (PNP: LEN005f PNP0f13) says it can support a different bus. If i2c-hid and hid-rmi are not used, you might want to try setting psmouse.synaptics_intertouch to 1 and report this to linux-input@vger.kernel.org. /me sets the option and reboots And, still not using SMBus :-/ [ 1.999715] psmouse serio1: synaptics: Trying to set up SMBus access [ 2.002534] psmouse serio1: synaptics: SMbus companion is not ready yet Looks I need to look into this more later. For the record. On the P71 I am seeing with 4.12.8: [ 1.994517] psmouse serio1: synaptics: Your touchpad (PNP: LEN001e PNP0f13) says it can support a different bus. If i2c-hid and hid-rmi are not used, you might want to try setting psmouse.synaptics_intertouch to 1 and report this to linux-input@vger.kernel.org. [ 2.055713] psmouse serio1: synaptics: Touchpad model: 1, fw: 8.2, id: 0x1e2b1, caps: 0xf405a3/0x940300/0x2e800/0x400000, board id: 3149, fw id: 2517820 Have you tried setting psmouse.synaptics_intertouch? Yes, with the option I got the messages about the SMBus companion not being ready. Unfortunately we need to send back the hardware this week, so I don't think that I can look into the issue more for a while at least. |
