Touchpad slow or imprecise

Would be nice to try and use the rmi4 protocol over smbus instead of the ps/2 emulation. As of yet, kernel 4.12-rc0 doesn't do this. modprobe psmouse synaptics_intertouch=1 can force it.

Trackpoint recognized as 'ImPS/2 Generic Wheel Mouse'

and thus middle button scrolling is not enabled. work around:

xinput set-prop "ImPS/2 Generic Wheel Mouse" "libinput Scroll Method Enabled" 0 0 1

X doesn't see KEY_KEYBOARD/KEY_FAVORITES from 'ThinkPad Extra Buttons' input device

Fn+F11 and Fn+F12

$ sudo libinput-debug-events --device /dev/input/event4

unknown acpi event

[ 3535.293188] thinkpad_acpi: unknown possible thermal alarm or keyboard event received
[ 3535.293192] thinkpad_acpi: unhandled HKEY event 0x60b1
[ 3535.293194] thinkpad_acpi: please report the conditions when this event happened to [email protected]

ps. should be fixed in 4.12-rc1, probably by 696c6523.

Hi,

Do you know how to change the sensitivity of the TrackPoint?

@gdamjan, thanks for those notes ;-)

unknown acpi event 0x60b1, 0x60b0 doesn't seem to be fixed for me with kernel 4.13.12-1-ARCH ;(

Same here on 4.15.13, still happening. Where can I find information on how to fix this? Should I switch my Kernel? To which one? How?

Too many questions, I know. Just answer one please and I'll go along. Thanks!

Here's some information which might interest whoever is looking at this page: https://gist.github.com/zmalltalker/3149710
