Hello all! I am experiencing an issue on a new Thinkpad Yoga S1 which implements a touchpad with integrated buttons - I assume this is called a button-pad? And as with all Thinkpads it also has a trackpoint (the red knob) as well as a touchscreen and a graphics tablet integrated into the display (AFAIK Wacom). All pointing devices work properly for pointing - I can move the mouse cursor smoothly without any glitch, also using the touchpad. The touchscreen and the Wacom also work for "clicking". But as soon as I press one of the buttons on the touchpad I get a strange behavior. Either the cursor randomly jumps and causes random button presses and then freezes for some seconds or it just freezes. In kernel dmesg I see the following when this happens: [ 38.880242] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 [ 38.881295] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 [ 38.882452] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 [ 38.883558] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 [ 38.884662] psmouse serio1: TouchPad at isa0060/serio1/input0 lost sync at byte 1 [ 38.884673] psmouse serio1: issuing reconnect request Soon after the reconnect request it starts working again, i.e. I can move the cursor again but if I press a button on the touchpad it starts to fail again. In dmesg I also see this output after boot: [ 2.106803] psmouse serio1: synaptics: Touchpad model: 1, fw: 8.1, id: 0x1e2b1, caps: 0xd001a3/0x940300/0x127c00, board id: 2911, fw id: 1514409 [ 2.106813] psmouse serio1: synaptics: serio: Synaptics pass-through port at isa0060/serio1/input0 [ 6.584970] psmouse serio2: alps: Unknown ALPS touchpad: E7=10 00 64, EC=10 00 64 [ 8.532572] psmouse serio2: trackpoint: IBM TrackPoint firmware: 0x0e, buttons: 3/3 Do I have a not yet supported touchpad here? Or does my hardware have a defect? The main issue I have now is that I just bought this Thinkpad and I need to know if this is a software or a hardware issue. If it is software it can surely be fixed and I can wait for that to happen (or even try to help doing it). But if it is hardware I need to return the machine ASAP - which would be the worst case. If you have an idea what I might do to either fix that or help to debug I would be very happy if you would let me know. Many thanks!
