This makes touchpad on Lenovo Yoga 530 doensn't work as expected. [Fix] Sync the MP2 driver with upstream version. [Test] The new upstream driver doesn't break on Latitude 5495. Users haven't given any feedback yet, but since Disco is freezing I am sending this out. [Regression Potential] Low. It's from upstream, and only a subset of Raven Ridge has this device. === Original Bug Report === The touchpad is not working and does not show up in cat /proc/bus/input/devices on multiple kernels. I've tried the newest kernel to date (19.08.18) and a few others. The touchpad works on windows. --- ProblemType: Bug ApportVersion: 2.20.9-0ubuntu7.2 Architecture: amd64 CurrentDesktop: ubuntu:GNOME DistroRelease: Ubuntu 18.04 InstallationDate: Installed on 2018-08-18 (0 days ago) InstallationMedia: Ubuntu 16.04.5 LTS "Xenial Xerus" - Release amd64 (20180731) Package: linux (not installed) Tags: bionic Uname: Linux 4.18.3-041803-generic x86_64 UnreportableReason: The running kernel is not an Ubuntu kernel UpgradeStatus: Upgraded to bionic on 2018-08-18 (0 days ago) UserGroups: adm cdrom dip lpadmin plugdev sambashare sudo _MarkForUpload: True To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1787775/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : firstname.lastname@example.org Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
