 Posted: Thu Jan 02, 2025 10:06 am Post subject: grpahical UI for modifying libinput props/parameters |
 |
|
I have a laptop with a touchpad, driven by libinput under X.
I want to tune its parameters - acceleration etc.
I can do "xinput list-props -d xxx" and then set prop to different values, but this is not very efficient.
The ArchWiki suggests (https://wiki.archlinux.org/title/Libinput#Graphical_tools)
multiple graphical UIs for that, however all of them require a heavy DE: Gnome, KDE, ....
...which I do not have, just a simple WM.
Is there a simple, standalone, graphical X tool to play around with libinput parameters?
Thank you! |

I would just set it once by hand in some filie like
/etc/xorg.cond.d/90touchpad.conf
and forget about it. On my laptop I still use synaptics drivers, so I created the file with the following content
| Code: |
$ cat /etc/X11/xorg.conf.d/90-SynPS2-Synaptics-touchpad.conf
Section "InputClass"
# Identifier and driver
Identifier "SynPS/2 Synaptics TouchPad"
MatchIsTouchpad "true"
Driver "synaptics"
Option "TapButton1" "1"
Option "LeftEdge" "120"
Option "RightEdge" "1800"
Option "TopEdge" "60"
Option "BottomEdge" "1000"
Option "EmulateMidButtonTime" "75"
Option "VertEdgeScroll" "1"
Option "HorizEdgeScroll" "1"
Option "CornerCoasting" "0"
Option "CoastingSpeed" "10"
Option "CoastingFriction" "5"
Option "VertScrollDelta" "48"
Option "HorizScrollDelta" "48"
#Option "MinSpeed" "0.60"
#Option "MaxSpeed" "1.10"
#Option "AccelFactor" "0.030"
#Option "EdgeMotionMinSpeed" "200"
#Option "EdgeMotionMaxSpeed" "200"
Option "CircularScrolling" "1"
Option "CircScrollDelta" "0.1"
Option "CircScrollTrigger" "7"
Option "GrabEventDevice" "0"
EndSection

and did not touch it for already 7 years. In you case identifier will be different, Device will be libinput, and then the list of parameters.
The values you can tweak with xinput on the running server to find the best, and then record them in this file for future. |

If you don't find anything else, you could try xfce4-settings. If you set -upower -xklavier for it, there may only be two additional dependencies: | Code: | [ebuild N ] xfce-base/garcon-4.18.2::gentoo USE="-introspection" 566 KiB
[ebuild N ] xfce-base/exo-4.18.0::gentoo 876 KiB
[ebuild N ] xfce-base/xfce4-settings-4.18.6-r1::gentoo USE="libnotify -colord -libcanberra -upower -xklavier" INPUT_DEVICES="libinput" PYTHON_SINGLE_TARGET="python3_12 -python3_10 -python3_11 -python3_13" 1,524 KiB |
I also have xfce-base/xfconf and xfce-base/libxfce4ui, so maybe one or both of those might be needed too. I don't use or otherwise have xfce4 installed.
Perhaps not ideal, but maybe usable.
