https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D228875 Oleksandr Tymoshenko <gonzo@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|New |Closed CC| |gonzo@FreeBSD.org Resolution|--- |Works As Intended Assignee|bugs@FreeBSD.org |gonzo@FreeBSD.org --- Comment #6 from Oleksandr Tymoshenko <gonzo@FreeBSD.org> --- The problem is not in the kernel it's in xf86-input-synaptics driver. The trackpad sends all events to the driver as a Synaptics packets that are supposed to contain all the information:number of presspoints, movements, "button" states. The trackpoint/buttons events also reported the same way as "guest device" events and can be detected by checking "finger width" field value in a packet to be equal 3 (see sys/dev/atkbdc/psm.c line 3268 and bel= ow). The xf86-input-synaptics switches /dev/psm0 "native" mode that disables all= the in-kernel processing of synaptics packet and makes kernel pass them to the userland as-is for further handling. The problem is that xf86-input-synapti= cs doesn't have code to handle guest device events and so the trackpoint and physical buttons do not work. I ended up using xf86-input-libinput on my Thinkpad for the gestures/synpat= ics support. I think it requires some changes in kernel config and some X11 dri= vers before it can be made default for the release. Closing this issue as "works as intended" because it can't be fixed in Free= BSD code. I am not sure if xf86-input-synaptics is actively maintained but I th= ink it's worth reporting the issue to the upstream. --=20 You are receiving this mail because: You are the assignee for the bug.=
