Hi, I am experiencing a similar issue with the new Lenovo Yoga 720 15" that just came out (April 2017)
As far as I can tell the touchpad is not detected. I have tried all of the option suggested above to no avail. Please let me know if I should file a new bug or if I can provide any additional troubleshooting information. Thanks. $ xinput --list ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ Wacom HID 50FE Finger id=11 [slave pointer (2)] ⎜ ↳ Logitech G300s Optical Gaming Mouse id=15 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Video Bus id=8 [slave keyboard (3)] ↳ Power Button id=9 [slave keyboard (3)] ↳ EasyCamera id=10 [slave keyboard (3)] ↳ Ideapad extra buttons id=12 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=13 [slave keyboard (3)] ↳ Logitech G300s Optical Gaming Mouse id=14 [slave keyboard (3)] -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1641393 Title: 'Elan Touchpad' not detected in Ubuntu 16.04.1 Gigabyte P57K-965-603S Fresh install To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1641393/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
