Subject: hwdb: fix Lenovo B570e touchpad ABS ranges for edge scrolling (#43264)
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=855285b07e8f4868da9870f9053033477df74e9c;p=thirdparty%2Fsystemd.git

hwdb: fix Lenovo B570e touchpad ABS ranges for edge scrolling (#43264)

The Lenovo B570e touchpad (ETPS/2 Elantech) reports ABS ranges that
are too wide by default, which makes edge scrolling trigger across
roughly the right half of the touchpad instead of only at the right
edge. Add an evdev hwdb entry in `60-evdev.hwdb` that overrides the
ABS_X/ABS_Y (and the matching MT position) ranges with the calibrated
values, following the same pattern already used for the Lenovo B590
and L430 entries.

Fixes #29666
