evemu recording to reproduce the bug
System setup:
- Asus UX410UA laptop with i5-7200U CPU, Intel HD 620 graphics and French
(AZERTY) keyboard
- Arch Linux, freshly updated at the time of writing (2017-08-16)
- Touchpad dimensions (as measured with a ruler, might be a little inaccurate):
103x73mm
- gnome-desktop 1:3.24.2-1
- libinput 1.8.1-1
- linux 4.12.6-1
- Tap-to-click and reverse scrolling enabled in GNOME settings
ISSUE: cursor sometimes starts jumping around erratically in response to human
input, and stops after some keyboard input. See attached evemu-record output to
reproduce. The bug occurs after just a few seconds. I've been unable to
determine what triggers the bug; I started evemu-record after the trackpad
started having the issue, which occurs once or twice a day.
Output of relevant commands:
