how to save Xorg mouse/trackpoint sensitivity settings?

[GNUser]

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?

[GNUser]

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.

[GNUser]

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:

Code: [Select]

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

# the above properties look very different than what I see in TCL 10.1 with the default xf86-input-evdev
# note that Accel Speed is property #325

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.

[GNUser]

Thanks, curaga. Good to know evdev will be around for a while.

BTW, I discovered that this also works (and is much more intuitive):

Code: [Select]

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)
