I do not believe I owned this laptop far enough back to have installed
15.10. I believe the first installation I put on it was 16.04.
Additionally, I tried the kernel boot param of "i8042.kbdreset=1". When
I booted up the next time I saw the following output from xinput:
$ xinput
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PS/2 Elantech Touchpad id=14 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ Sleep Button id=9 [slave keyboard (3)]
↳ Yubico Yubikey 4 OTP+U2F+CCID id=10 [slave keyboard (3)]
↳ Lenovo EasyCamera id=11 [slave keyboard (3)]
↳ Ideapad extra buttons id=12 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)]
But almost as soon as I started to move the pointer around the touchpad
locked up (pointer stopped responding) for about 5-10 seconds and then
started working again, but now the output of xinput looked like:
$ xinput
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ PS/2 Logitech Wheel Mouse id=14 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ Power Button id=8 [slave keyboard (3)]
↳ Sleep Button id=9 [slave keyboard (3)]
↳ Yubico Yubikey 4 OTP+U2F+CCID id=10 [slave keyboard (3)]
↳ Lenovo EasyCamera id=11 [slave keyboard (3)]
↳ Ideapad extra buttons id=12 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)]
Checking out dmesg, I saw:
[ 33.327457] psmouse serio1: Touchpad at isa0060/serio1/input0 lost
synchronization, throwing 2 bytes away.
[ 33.880155] psmouse serio1: resync failed, issuing reconnect request
[ 37.823561] psmouse serio1: Failed to deactivate mouse on isa0060/serio1
[ 38.259688] input: PS/2 Logitech Wheel Mouse as

[ 38.381415] systemd[1]: motd-news.timer: Adding 25min 26.475299s random time.
So, as you can see, even when it does get detected as a touchpad it will
not remain functional for long.
I hope this helps!

Title:
ETPS/2 Elantech Touchpad inconsistently detected (Lenovo Y700 15ISK)
Status in linux package in Ubuntu:
Confirmed
Bug description:
This has been happening reliably on my Lenovo Y700 15ISK since
15.10... Sometimes it shows up as ETPS/2, sometimes PS/2, sometimes
Logitech Wheelmouse... Most of the time it shows as "PS/2 Logitech
Wheel Mouse" but none of the multitouch (2 finger scroll, 3 finger
middle-click) can be set up. synclient says no device is present.
