unless I'm reading that wrong, the kernel reports exactly the same range as the touchpad sends, so there should be no need for the hwdb to carry x/y values overridding the kernel-reported ranges In upstream systemd, this commit was added for your system's touchpad: https://github.com/systemd/systemd/commit/2ceefe45873d0265fb99bc5757593e5bbb2c732b That commit is included in focal. If that isn't working right for you, I'd suggest opening a merge request, or at least a bug, upstream so they can review/accept any further changes, and if accepted we can consider backporting the change. ** Changed in: libinput (Ubuntu) Status: New => Invalid ** Changed in: systemd (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to systemd in Ubuntu. https://bugs.launchpad.net/bugs/1896540 Title: Incorrectly specified Touchpad size for Lenovo T490 Status in libinput package in Ubuntu: Invalid Status in systemd package in Ubuntu: Incomplete Bug description: The vertical sensitivity of the touchpad on my laptop Lenovo T490 seemed significantly higher than the horizontal sensitivity.
