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? More info: $ dmesg | grep -i "ps/2" [ 2.497642] i8042: PNP: PS/2 Controller [PNP0303:PS2K,PNP0f13:PS2M] at 0x60,0x64 irq 1,12 [ 2.502081] mousedev: PS/2 mouse device common for all mice [ 15.025069] input: PS/2 Generic Mouse as /devices/platform/i8042/serio1/input/input11 [ 226.680273] input: PS/2 Mouse as /devices/platform/i8042/serio1/input/input17 [ 226.698384] input: AlpsPS/2 ALPS GlidePoint as /devices/platform/i8042/serio1/input/input18
