Title:
Touchpad not detected in Lenovo X1 Yoga / Yoga 720-15IKB
To manage notifications
I have managed to get my Yoga 720 15"'s touchpad working in Linux Mint
(based on Ubuntu)
It's a fairly straightforward issue + patch (missing PCI ID)
Need to re-compile intel-lpss-pci module
On this line: https://github.com/torvalds/linux/blob/master/drivers/mfd
/intel-lpss-pci.c#L224

I also tried adding this line:
alias usb:v06CBp00081*dc*dsc*dp*ic*isc*ip*in* synaptics_usb
to a file: /etc/modprobe.d/local-aliases.conf
I formatted the line in analogy to lines with usb:v06CB in
/lib/modules/4.13.0-999-generic/modules.alias
/sys/kernel/debug/usb/devices still show "Driver=(non
I compiled 4.13rc1 including the patch adding the ELAN0651 to the acpi device
id array.
It did not help. I think the device is connected over USB:
$ lsusb -vv

There was some discussion here:

I just tried Kernel 4.13 RC2. Nothing changed.
I did not test your "ELAN0651" patch. Maybe both together could enable the
touchpad...
However, it would be really helpful to me, if someone could give me a
direction, how I can debug this problem.
"cat /sys/bus/i2c/devices/*/name" does not show any
I just checked my dmesg:
If ACPI is the problem, shouldn't dmesg show some "elan0651" device (although
it does not bind any driver to it)?
So, if I cannot find any "elan" string in my dmesg, this should mean that the
kernel does not find ANY i2c device with a similar hardware name, shouldn't it?
There was a commit regarding the elan_i2c driver:

Sorry, forgot to mention the most important bit of information: that did not
solve the problem.
Nor did adding "acpi=biosirq" or "i8042.reset" to the kernel line (solutions
reported for other computers with similar problems).
Secure boot was disabled throughout. (I have no idea why legacy boot

This sounds like a problem with SecureBoot.
Did you disable UEFI SecureBoot?
How about the touchpad? Is it working with your kernel?

I managed to boot the kernel I had compiled with the above patch (but
not based on 4.12.1 but on 4.8.0). I needed to change to legacy boot
mode in BIOS to get it to boot.

I am using Ubuntu 16.04.2, currently running the default
4.8.0-58-generic kernel (works fine except for the touchpad not being
detected, had to switch sata mode from raid to ahci for it to detect the
ssd though).

I could test this patch on my own notebook as soon as I got some spare
time...

Touchpad not detect
I am affected by this bug as well (Lenovo Yoga 720-15IKB, touchpad not
detected).
I tried the mainline kernel (4.12.1) but I only see "Loading initial
ramdisk ..." and it appears to hang. (removing "quiet" has no effect).
I wanted to try if this diff would fix the problem (hwid from windows devic
I attached parts of the requested dmesg to this comment.
Is this enough information? I'm a little bit afraid of posting my full dmesg,
due to privacy...
(Maybe someone could tell me, how I can automatically censor MAC addresses /
other sensitive information..?)
** Attachment added: "dmesg |grep
Add "i2c_hid.dyndbg=+p" to the kernel parameter, reboot, then attach
`dmesg` here, thanks.
