Sorry for my late reply. Linux v4.17 gave me the same identical issue. I could not easily post here at the time because of the AppArmor bug.
Now I reinstalled (x)ubuntu 17.10 on my laptop, and after I upgraded Linux to the v4.15-rc3 from the mainline, the trackpad works perfectly. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1721809 Title: The touchpad doesn't work on Lenovo Ideapad 320 To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1721809/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
