All touchpad features were working fine until I received in 15.04 the automatic update to kernel version 3.19.0-22. This kernel introduced a condition in which, at times, the system started randomly registering keyboard input when pointing with the touchpad. The original bug got apparently fixed in kernel version 3.19.0-25, but as a result this kernel version broke completely all tap-events for my touchpad. They are not registering at all. Pointing and scrolling work, so do the mechanical click-switches in the corners, but tapping or sweeping with one or more fingers does not get registered even though the settings were never touched. I now got kernel update to 3.19.0-26, but the bug persists in this version, too. At the moment I had to revert back to kernel version 3.19.0-16 in order to be able to use my touchpad normally. --- ApportVersion: 2.17.2-0ubuntu1.4 Architecture: amd64 AudioDevicesInUse: USER PID ACCESS COMMAND /dev/snd/controlC0: samuli 1172 F.... pulseaudio /dev/snd/controlC1: samuli 1172 F.... pulseaudio CurrentDesktop: X-Cinnamon DistroRelease: Ubuntu 15.04 HibernationDevice: RESUME=UUID=caec55c5-801b-4ddb-81bf-ab7d116a7c9e InstallationDate: Installed on 2014-06-24 (449 days ago) InstallationMedia: Ubuntu 14.04 LTS "Trusty Tahr" - Release amd64 (20140417) IwConfig: eth1 no wireless extensions. lo no wireless extensions.
