--- Comment #3 from David D <david.ducas...@gmail.com> --- This is not a hardware issue : on the same computer (dual boot), the touchpad does work with Windows 10 and Trisquel 8 (based on Ubuntu 16.04). The trouble sometimes appeared when a terminal window (Konsole) is open, after doing a double click in the title to maximize the window. But I can not reproduce it every time :( . This might be a kernel issue (currently version 4.15.0-38-generic) but I have no idea how to report it... -- You are receiving this mail because: You are watching all bug changes.
