Title:
Trackpoint device not working by default on Thinkpad L570
Status in linux package in Ubuntu:
Confirmed
Bug description:
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.
