I want to add that the touchpad dropout issues affect the Lenovo Thinkpad T460s series as well. I got things working by downloading and installing the latest libinput packages for cosmic (unstable) from https://launchpad.net/ubuntu/+source/libinput. I installed libinput10, libinput-bin, and libinput-tools 1.12.0-1.
History: When I first got this T460s I found the touchpad would drop out frequently in ubuntu. I got around this by using the synaptics driver (package xserver-xorg-input-synaptics) instead of libinput. But the synaptics driver has palm detection behavior that I couldn't get working, so I was constantly doing things like selecting and replacing text unintentionally while typing. Today I found a series of Fedora bug reports on this issue with these Thinkpads, culminating in https://bugzilla.redhat.com/show_bug.cgi?id=1572394 which suggested that a fix was included in libinput 1.10.5.3 (not sure when exactly it was introduced). These bug reports indicate that the Trackpoint device on the affected Thinkpads is prone to sending spurious events that trigger the palm detection behavior in libinput. Disabling the Trackpoint device thus fixes the touchpad drop-outs. With the later version of libinput my T460s touchpad and trackpoint are working great, and I have good palm detection behavior. Woohoo! Consider this a vote in favor of the SRU. ** Bug watch added: Red Hat Bugzilla #1572394 https://bugzilla.redhat.com/show_bug.cgi?id=1572394 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1767559 Title: Provide libinput 1.10.7 in bionic-updates to fix specific touchpad and keyboard issues To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libinput/+bug/1767559/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
