No. The laptop is a 2017 model. The source file in question simply doesn't have an array element that describes/identifies the trackpad.

@CoolStar You have to change the bios to AHCI for the USB thumbdrive install image to boot. At least for me. I mean, we all have the same Yoga 720 15" laptop, right? I didn't want to toast my Windows 10 install, so I resized the Windows partition to 1/2, leaving 1/2 for Ubuntu.

The way to submit upstream, I think, is to fork the kernel repository, apply the patch, then submit a pull request. Once you've pushed your changes to your fork, there will be a button on the github page (for your fork) to create the Pull Request.

[Bug 1700657] Re: Touchpad not detected in Lenovo X1 Yoga / Yoga 720-15IKB
I must say the 720 is zippy to use. It took me 36-38 minutes to do a complete kernel build. apt-et update/upgrade takes just a few seconds. At least with KDE (other desktops may vary), I was able to adjust the font sizes, and other window decorations and the like to make the environment look great (to me) in 4K resolution. I don't think the kernel recognized the NVIDIA graphics at all. Nothing in dmesg. The fingerprint reader doesn't work with any of the suggested packages. That would be sweet - to be able to log in and do sudo password with the fingerprint reader instead of typing. Otherwise, I haven't seen much that doesn't work. It suspends and resumes proper. I guess the only other nit is that sometimes I have to power cycle/reboot one or more times to get the machine to boot into Ubuntu. Certainly sudo reboot does reboot into a black screen every time (that I've seen so far). -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1700657 Title: Touchpad not detected in Lenovo X1 Yoga / Yoga 720-15IKB To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1700657/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1700657] Re: Touchpad not detected in Lenovo X1 Yoga / Yoga 720-15IKB
@bjorn I have come to the same conclusion. THere's something about the kernel build process that yields a kernel that won't work due to some setting in the BIOS. Yet kernels on the install media and from apt-get dist-upgrade do work fine. I tried turning on and off secure boot, etc., with no luck. I don't want to toast my windows install, so some of the bios settings I didn't want to touch. The funny thing is I will probably not use the windows install so much, but it's the only real windows on hardware I have. Linux does look outstanding on the 720, except for the trackpad issue. I have several linux boxes here that I use and am into docker and AWS and other services that use it. Going back to use windows 10 after not using windows for several years was just terrible.
