I have not performed a full survey but can give you links to various complaints on distro forums, a large thread on the Logitech support forums and more.

Well, I appreciate the efforts that you put in it, but based on received reports, I think that enabling tap by default is something that better serves users. (Personally I only connected the T650 today to test the issue reported by a user.) AFAIK KDE only has a "Mouse Click Emulation" option which, when enabled, would change the laptop touchpad behavior (it did not change the T650 setting when plugged in). If libinput already has a hwdb where the default can be set, why should every application duplicate the detection of this device? What are the drawbacks of doing this in libinput? While searching I found only one report that is not strictly related to disabling tapping, but a bad pressure threshold: <a href="https://askubuntu.com/questions/796546/logitech-touchpad-t650-problem-working-fine-on-ubuntu-14-10-but-not-on-any-oth">https://askubuntu.com/questions/796546/logitech-touchpad-t650-problem-working-fine-on-ubuntu-14-10-but-not-on-any-oth</a></pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the assignee for the bug.</li> </ul> </body> </html>
