https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D228668 Bug ID: 228668 Summary: [psm] Alps GlidePoint on HP EliteBook 1040 G3: No two finger scroll Product: Base System Version: CURRENT Hardware: Any OS: Any Status: New Severity: Affects Only Me Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: neel@neelc.org Created attachment 193905 --> https://bugs.freebsd.org/bugzilla/attachment.cgi?id=3D193905&action= =3Dedit HP EliteBook 1040 G3 psm snippets I just got a HP EliteBook 1040 G3 to replace an older 1040 G1, and am not a= ble to do two finger scroll. I tried this with enabling Synaptics and Elantech support in /boot/loader.conf, and tried both with and without moused. If I = put two fingers on the touchpad, the cursor does not move, but the page does not scroll. Unlike the 1040 G1 or G2 which used a Synaptics "ForcePad" (pressure sensit= ive touchpad like Apple's "Force Touch"), the 1040 G3 uses a ClickPad, but one backed by an Alps GlidePoint instead of Synaptics or Elantech. Looking at psm.c, I did not see any code for two finger scrolling on Alps touchpads (It seems Dell Latitudes and E-series ThinkPads also use GlidePoints, and both **probably** have this issue). There is an Hackintosh touchpad driver which seems interesting: https://github.com/RehabMan/OS-X-Voodoo-PS2-Controller They even have a driver for multiple trackpads, including Alps units: https://github.com/RehabMan/OS-X-Voodoo-PS2-Controller/tree/master/VoodooPS= 2Trackpad (maybe at the files VoodooPS2ALPSGlidePoint.cpp and VoodooPS2ALPSGlidePoint= .h?) I have attached psm snippets, and will attach my full dmesg log. --=20 You are receiving this mail because: You are the assignee for the bug.=
