Just as a usage report after a while: I mostly have to reboot the device after first boot again, as the recognition of the two/three finger gestures isn't working correctly aswell as the scrolling. It appears then that after using such gestures, the mouse hangs in the gesture mode. E.g. after scrolling with two fingers it stays in scroll mode even with only one finger until I scroll again.
If I reboot the device again, this behaviour is fixed for the uptime. Apart from that: I had more and more problems, that my ssd out of a sudden disappeard from the system. I found the following kernel parameter that fixed it for me: nvme_core.default_ps_max_latency_us=0 Would be nice to hear if others have these things aswell, or if it's only me.

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 : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
