Public bug reported: Upstream has released -synaptics 1.7.99.1:
A snapshot of what will be synaptics 1.8. There are a couple of significant changes in here: libevdev support: The evdev backend on Linux now uses libevdev. We recommend to use libevdev 1.1-rc1 or later as the synaptics driver is very likely to trigger SYN_DROPPED and we've fixed a bunch of issues in libevdev 1.1. Support for T440, T540, X240, Helix, Yoga: The bulk of the changes is to support this set of Lenovo touchpads. These touchpads don't have separate physical buttons for the trackstick and need to be emulated as software-button by the driver. TouchpadOff behaviour change: Synaptics has a property "Synaptics Off" to disable events. Previously, this disabled any event from the touchpad. Now, physical button clicks are allowed even when the touchpad is disabled. mtdev was dropped: There are no touchpad drivers in the kernel tree that use protocol A, so using mtdev is just a computationally expensiv and memory-wasting noop. this needs a newer libevdev too. ** Affects: libevdev (Ubuntu) Importance: Undecided Status: New ** Affects: xserver-xorg-input-synaptics (Ubuntu) Importance: Undecided Status: New ** Also affects: libevdev (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-input-synaptics in Ubuntu. https://bugs.launchpad.net/bugs/1294515 Title: FFE: new upstream version to support touchpads on newer Lenovo models To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libevdev/+bug/1294515/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
