Hello guys. I’ve just installed openSUSE 42.3 in my Lenovo Yoga 720 15 inch and everything went absolutely fine except for one thing: the touchpad does not work. I’m using openSUSE and Windows 10 at the same time, and touchpad works in Windows OS.
It seems touchpad is unrecognized, and I think there are other Yoga users facing the same problems in Ubuntu and Arch Linux.
Post #18 of the bug report you linked to seems to hold the solution (involving recompiling the intel-lpss-pci module to include the device chipset used in the Yoga 720). It’s not an easy task for a newbie, but not impossible either.
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
Add “{ PCI_VDEVICE(INTEL, 0xa162), (kernel_ulong_t)&spt_uart_info },”
Recompile and install the new intel-lpss-pci module and touchpad will work.
It might be easiest to submit a bug report for this and see if the patch can be backported for a Leap kernel.
