Most likely the kernel. However, I can't see any obviously relevant
changes. What does this command show:
ls -l /sys/class/input/mouse*/device/device/driver
-- $ ls -l /sys/class/input/mouse*/device/device/driver
lrwxrwxrwx 1 root root 0 Apr 6 06:34
/sys/class/input/mouse0/device/device/driver ->
../../../../bus/serio/drivers/psmouse
lrwxrwxrwx 1 root root 0 Apr 6 06:34
/sys/class/input/mouse1/device/device/driver ->
../../../../../../../../bus/hid/drivers/hid-generic
lrwxrwxrwx 1 root root 0 Apr 6 06:34
/sys/class/input/mouse2/device/device/driver ->
../../../../../../../../bus/hid/drivers/hid-multitouch
$ sudo modprobe -r psmouse
$ sudo modprobe psmouse
Makes it "work" again. ...
I also confirm that
sudo modprobe -r psmouse && sudo modprobe psmouse
works and after that command the touch-pad is working.
Magic key-codes, send a key code every 2s or some such to indicate
laptop unfold angle, such that when it's beyond 180 open the keycodes
spam stops and thus OS should turn off keyboard and touchpad because
it's now in "tablet" mode. It folds all the way out.
I also have magic codes:
[ 386.645269] atkbd serio0: Unknown key released (translated set 2,
code 0xbe on isa0060/serio0).
[ 386.645281] atkbd serio0: Use 'setkeycodes e03e <keycode>' to make it
known.
But these magic codes did appear also pre 8.4 time.
I also tried reverting back to linux-image-3.16.0-4-amd64 ckt20-1+deb8u4
but that did not help.
I have Yoga 13 non-Pro model.
