No. The laptop is a 2017 model. The source file in question simply doesn't have an array element that describes/identifies the trackpad. My assumption is that the driver maintainer simply hasn't seen a device with this ID before.
I would be happy to test the latest kernel, but I don;'t see the required fix in the source code. https://github.com/torvalds/linux/blob/master/drivers/mfd/intel-lpss- pci.c#L223 (the missing line is after that one) If this is not the correct kernel source, please let me know. This is master/4.13-rc3 branch. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1710392 Title: Additional initializer needed to recognize trackpad on Lenovo Yoga 720 laptop Status in linux package in Ubuntu: Incomplete Bug description: There's just a 1 line patch required, to add an initializer to array of structs scanned to match up the device ID with driver. The PR is here: https://github.com/torvalds/linux/pull/444#discussion_r131229815 I've applied the patch and created and booted from a custom kernel and it works great. The laptop is wonderful running Ubuntu: I7 7700HQ, 16G RAM, 500G SSD, 4K touch screen, decent I/O ports.
