Hi all, I'm using Archlinux on a Dell Inspiron 7420 laptop, which has an ALPS touchpad that doesn't have driver in kernel. Currently aur/psmouse-alps-driver provides support for it. But recently some weird problem happened. After I switch off touchpad using `synclient TouchpadOff=1`, it should be completely turned off. But when I wipe it with palm, the mouse pointer randomly moves and sometimes even clicks! In `xinput list` there is a strange "PS/2 mouse" device: ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ RAPOO RAPOO 5G Wireless Device id=12 [slave pointer (2)] ⎜ ↳ AlpsPS/2 ALPS GlidePoint id=17 [slave pointer (2)] ⎜ ↳ PS/2 Mouse id=15 [slave pointer (2)] [..cut..] (The RAPOO is my USB mouse and it has nothing to do with the PS/2 device) I had to use xinput to disable the PS/2 device to stop the problem. Is there any other input device I don't know inside my laptop? Or, is it a bug?
