Most probably, it is not correctly detected on startup; dmesg shows kernel: [ 2.997182 ] input: AlpsPS/2 ALPS GlidePoint as /devices/platform/i8042/serio1/input/input6 As far as I understand it, "GlidePoint" only refers to a touch pad without track point. All events coming from the track point are consequently actively discarded, seen in dmesg as kernel: [ 2279.323441 ] psmouse serio1: alps: Rejected trackstick packet from non DualPoint device Searching for this problem I found this kernel developer discussion which seems related: https://patchwork.kernel.org/patch/9941661/ As suggested by one of the kernel developers there, I added "psmouse.proto=imps" as a kernel boot parameter. The touch pad and track point now show up in the system log as input: PS/2 Generic Mouse as /devices/platform/i8042/serio1/input/input6 And it works well now, just as it should. I also noted that the touch pad became a lot more usable at the same time. Previously (with the default installation) it was lagging and could produce pseudo clicks at random. I am submitting this report here in order to help improve the hardware detection in Ubuntu / linux kernel.
