I've noticed when using a graphical interface (Xorg-7.7 and fluxbox) in Pure64 11-beta that my mouse (actually a trackpoint, a.k.a. "nipple mouse") is much more sensitive than I'm used to in Pure64 10.1. The difference makes it difficult for me to control the pointer.
I have 10.1 and 11-beta in two separate partitions. Can you please help me figure out what I need to transfer from 10.1 to 11-beta so that the trackpoint behaves similarly?
-
The change I'm experiencing may be due to different defaults in xf86-input-evdev (tcl 10.x) vs xf86-input-libinput (tcl 11.x):
https://wiki.archlinux.org/index.php/TrackPoint
I'm going to explore /sys/devices/platform/i8042/serio1/ to see if the attributes in 10.x vs 11.x are different.
-
Strangely, all attributes in /sys/devices/platform/i8042/serio1/ are identical between 10.1 and 11-beta.
In that case, I'm at a loss for how to make xf86-input-libinput react to my TrackPoint in the same way as xf86-input-evdev.
If anyone knows, please share.

SOLVED.
It turns out that the two input libraries present very different device properties to X, so I don't think it will be possible to replicate the TrackPoint behavior exactly.
This is in TCL Pure64 11-beta using the default xf86-input-libinput:
bruno@box:~$ xinput --list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ TPPS/2 IBM TrackPoint id=10 [slave pointer (2)]
⎣ Virtual core keyboard id=3 [master keyboard (2)]
↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)]
↳ Power Button id=6 [slave keyboard (3)]
↳ Video Bus id=7 [slave keyboard (3)]
↳ AT Translated Set 2 keyboard id=9 [slave keyboard (3)]
# note that id of TrackPoint is 10
bruno@box:~$ xinput list-props 10

bruno@box:~$ xinput set-prop 10 325 -0.4
Now TrackPoint is better behaved. Not identical to xf86-input-evdev defaults, but tolerable. I'll get used to it.
-
You can install evdev. Even though libinput is considered the future, old drivers won't stop working for many years.
-
Thanks, curaga. Good to know evdev will be around for a while.
-
BTW, I discovered that this also works (and is much more intuitive):
xinput set-prop 'TPPS/2 IBM TrackPoint' 'libinput Accel Speed' -0.4
I can also confirm the Arch wiki's claim that with libinput, TrackPoint+middle-button scrolling is turned on by default :) (with evdev, a few xinput set-prop lines were required to activate it)
