I have a Lenovo T60p laptop (amd64) currently running 6.2-stable (dmesg below). I last rebuilt from source on 2017-12-15, but a cvs-update of /usr/src today (2018-01-10) shows no changes, so this machine is fully up to date for -stable.
My problem is that the touchpad does not work: finger movements on the touchpad either have no effect on the X cursor, or sometimes result in small movements of the X cursor which are not proportional to the finger movement. For what it's worth, this same computer has in the past had its touchpad 'just work' under OpenBSD 4.9, 5.1, 5.4, 5.6, 5.8, and 6.0 (all initially -release and then -stable). As a temporary workaround I have plugged in a USB (wired) mouse, and I was delighted to see that it 'just worked'. What's even more peculiar is that _when_the_USB_mouse_is_plugged_in_ the touchpad works again! Any suggestions for reviving the touchpad (without plugging in a mouse)? Here are the dmesg for booting without a mouse plugged in (/var/run/dmesg.boot), then the dmesg after pluggin in the mouse and unplugging it once or twice: # cat /var/run/dmesg.boot OpenBSD 6.2-stable
