Matteo Dell'Amico, could you please advise which release prior to vivid specifically this wasn't an issue in?
If you don't know, it would need to be confirmed to root cause. Prior release ISOs are available via http://releases.ubuntu.com/ . ** Tags removed: kernel-bug-exists-upstream-4.3 ** Tags added: kernel-bug-exists-upstream-4.4-rc3 needs-bisect ** Changed in: linux (Ubuntu) Status: Confirmed => Incomplete -- 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/1512482 Title: Keyboard and touchpad malfunctioning on Thinkpad Twist Status in linux package in Ubuntu: Incomplete Bug description: I don't know if this is really a kernel bug or if it's any other component, please help me know how I can diagnose the problem better. This is a bug I have been experiencing with both 15.04 and 15.10, while this was not a problem with earlier distributions -- unfortunately, I don't remember which one in particular was actually working. I have a Thinkpad Twist -- a hybrid laptop with touchscreen. The touchpad almost never works (even though sometimes, erratically, it does). The keyboard sometimes stops working, and works again after a suspend/resume cycle. Sometimes it behaves as if a key is stuck. When running xinput --list, I don't see the touchpad. The touchscreen and external input devices connected via USB, however, work fine. I was thinking this was a hardware problem, but on the same machine with Windows the problem does not appear to present itself.
