Installing Ubuntu 17.10 on a ThinkPad L570 (L470 should be the same in this regard) leaves the trackpoint as well as the trackpoint buttons in a non-working state. 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.
