A bit like other questions on touchpads but with a twist, I think. The touchpad in this Lenovo IdeaPad Z360 had been acting up even when it ran Windows 7. I switched to an external USB optical mouse, but the thing often disappears, buttons stop working or pointer starts moving on its own.
xinput lists the following pointer devices:
⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ USB OPTICAL MOUSE id=10 [slave pointer (2)] ⎜ ↳ PS/2 Generic Mouse id=14 [slave pointer (2)]
"USB OPTICAL MOUSE" is external mouse. Is it possible that the two devices are fighting for control of the pointer and buttons? How can I disable "PS/2 Generic Mouse" and leave "USB OPTICAL MOUSE" reign unchallenged?
