Created attachment 1229227 [details] touchpad-edge-detector output systemd-231-10.fc25.x86_64 kernel-4.9.0-0.rc8.git0.1.fc26.x86_64 libevdev-1.5.5-1.fc25.x86_64 libinput-1.5.2-2.fc25.x86_64 dmidecode: System Information Manufacturer: HP Product Name: HP Spectre Notebook Version: Type1ProductConfigId Serial Number: CND6347KYS UUID: 49852227-5537-E611-B27E-EC8EB53AC549 Wake-up Type: Power Switch SKU Number: W2K28UA#ABA Family: 103C_5335KV G=N L=CON B=HP S=SPT Actual measurement of the pad is 95.2mm W x 56.8 H. But rounded it as 95x57 for touchpad-edge-detector which didn't accept decimals. Also, the attached file contains the results, but from the same boot and login, two runs of the tool yield different results: Touchpad sends: x [1202..5691], y [1083..4801] |^C Touchpad sends: x [1206..5691], y [1088..4808] - Touchpad sends: x [1205..5691], y [1083..4808] | Touchpad sends: x [1205..5691], y [1083..4808] /
If the difference is a few device units it doesn't matter, and it's usually caused by your finger reaching some part it didn't reach before - quite common at the edge of the touchpad. I'll get this upstream, thanks.
