I changed it to confirmed, although I am the reporter. I found the patch is missing in the ubuntu kernel source: https://git.launchpad.net/~ubuntu-kernel-test/ubuntu/+source/linux/+git /mainline-crack/tree/drivers/mfd/intel-lpss-pci.c -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1710392 Title: Additional initializer needed to recognize trackpad on Lenovo Yoga 720 laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1710392/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1710392 Title: Additional initializer needed to recognize trackpad on Lenovo Yoga 720 laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1710392/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Sorry, to answer the first question, the latest kernels do boot on the machine, the trackpad isn't recognized and doesn't respond to anything at all. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1710392 Title: Additional initializer needed to recognize trackpad on Lenovo Yoga 720 laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1710392/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1710392] Re: Additional initializer needed to recognize trackpad on Lenovo Yoga 720 laptop
Did this issue start happening after an update/upgrade? Was there a prior kernel version where you were not having this particular problem? Would it be possible for you to test the latest upstream kernel? Refer to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest v4.13 kernel[0]. If this bug is fixed in the mainline kernel, please add the following tag 'kernel-fixed-upstream'. If the mainline kernel does not fix this bug, please add the tag: 'kernel-bug-exists-upstream'. Once testing of the upstream kernel is complete, please mark this bug as "Confirmed". Thanks in advance.

I searched the WWW for any kind of solution to the trackpad not being recognized. There are several months of similar questions, but no resolution. Until this patch was made public/known.
