You have been subscribed to a public bug: Touchpad does not work most of the time. I think it randomly started working once, but on several other tries/reboots, it does not work.
The device in question: cat /proc/bus/input/devices I: Bus=0011 Vendor=0002 Product=000e Version=0000 N: Name="ETPS/2 Elantech Touchpad" P: Phys=isa0060/serio2/input0 S: Sysfs=/devices/platform/i8042/serio2/input/input9 U: Uniq= H: Handlers=mouse0 event4 B: PROP=1 B: EV=b B: KEY=e420 30000 0 0 0 0 B: ABS=661800011000003 Log messages: dmesg |grep mouse | tail [ 3573.938741] psmouse serio2: Touchpad at isa0060/serio2/input0 lost sync at byte 6 [ 3573.946967] psmouse serio2: Touchpad at isa0060/serio2/input0 lost sync at byte 6 [ 3573.955131] psmouse serio2: Touchpad at isa0060/serio2/input0 lost sync at byte 6 [ 3573.955133] psmouse serio2: issuing reconnect request [ 3574.292050] psmouse serio2: Touchpad at isa0060/serio2/input0 lost sync at byte 6 [ 3574.300438] psmouse serio2: Touchpad at isa0060/serio2/input0 lost sync at byte 6 [ 3574.308767] psmouse serio2: Touchpad at isa0060/serio2/input0 lost sync at byte 6 [ 3574.317016] psmouse serio2: Touchpad at isa0060/serio2/input0 lost sync at byte 6 [ 3574.327805] psmouse serio2: Touchpad at isa0060/serio2/input0 lost sync at byte 6 [ 3574.327813] psmouse serio2: issuing reconnect request Using the following workaround I can get it to work, but with limited functionality: https://askubuntu.com/questions/922092/lifebook-e546-touchpad-on-ubuntu-16-04 sudo modprobe -r psmouse sudo modprobe psmouse proto=imps The problem with this fix is that two finger scrolling is no longer possible with the touchpad and the laptop has no other way to scroll.
