This solves Debian Bug report 1008760: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1008760. Solution was inspired by this kernel bug report message: https://bugzilla.kernel.org/show_bug.cgi?id=204967#c15. My measured pad dimensions with a ruler were 85x44mm. But I decided to take the 2x size reported by the current kernel when invoking the touchpad-edge-detector command from the libdev-tools package. Because this comment claims that the old vs new kernel reportings differ by factor 2: https://bugzilla.kernel.org/show_bug.cgi?id=204967#c3 . Therefore I have used this command to get the new entry to 60-evdev.hwdb: "root@pb:~# touchpad-edge-detector 80x34 /dev/input/event2 Touchpad ETPS/2 Elantech Touchpad on /dev/input/event2 Move one finger around the touchpad to detect the actual edges Kernel says: x [0..1254], y [0..528] Touchpad sends: x [0..2472], y [-524..528] -^C Touchpad size as listed by the kernel: 40x17mm User-specified touchpad size: 80x34mm Calculated ranges: 2472/1052 Suggested udev rule: # <Laptop model description goes here> evdev:name:ETPS/2 Elantech Touchpad:dmi:bvnPackardBell:bvrV1.21:bd08/09/2012:br21.240:svnPackardBell:pnEasyNoteTS11HR:pvrV1.21:rvnPackardBell:rnSJV50_HR:rvrBaseBoardVersion:cvnPackardBell:ct10:cvrV1.21:* EVDEV_ABS_00=0:2472:31 EVDEV_ABS_01=-524:528:31 EVDEV_ABS_35=0:2472:31 EVDEV_ABS_36=-524:528:31 "
Files in this directory specify a description of hardware devices, in the form of mappings from modalias-like keys (which identify specific hardware devices) to udev properties. Files in this directory are not read by udev directly. Instead, man:systemd-hwdb(8) compiles them into a binary database. See man:hwdb(7) for an overview of the configuration file format, and man:systemd-udevd.service(8) for a description of the udev daemon. Use 'systemd-analyze cat-config udev/hwdb.d' to display the effective config.
