I put the file in /etc/udev/hwdb.d: pauljohn:hwdb.d$ cat dell-5510.hwdb # Dell Precision 5510 evdev:name:SynPS/2 Synaptics TouchPad:dmi:bvn*:bvr*:bd*:svnDellInc.:pnPrecision5510* EVDEV_ABS_00=::42 EVDEV_ABS_01=::43 EVDEV_ABS_35=::42 EVDEV_ABS_36=::43 pauljohn:hwdb.d$ sudo udevadm hwdb --reload hwdb: unrecognized option '--reload' I'm guessing my udevadm is not up to date? My systemd is version 229-4ubuntu7 Please advise. Meanwhile, Mr Google suggests that rebooting will do the hwdb automatically, I'll see if that does it.
