I am using Arch Linux with KDE plasma as my desktop. My kernel version is 5.16.16-arch1,1 and the kde plasma version is 5.24.3
I have a Lenovo p52 with a 4k screen.
My current issue is that my pointer moves much too slow for my liking. I've turned mouse acceleration off and have the sensitivity turned to the maximum of one.
What more can I do aside from set the pointer to skip pixels?
Any help is appreciated.
Below is a snippet of the xinput list-props command. If I need to add more information, please let me know.
libinput Accel Speed (344): 1.000000
libinput Accel Speed Default (345): 0.000000
libinput Accel Profiles Available (346): 1, 1
libinput Accel Profile Enabled (347): 0, 1
libinput Accel Profile Enabled Default (348): 1, 0

So upon further investigation, I found this issue. https://gitlab.freedesktop.org/libinput … issues/733
It references the use of quirks for lib input. I have attempted to add a quirk for my trackpad but have been unsuccessful.
What I currently have is:
[Elan Touchpad]
MatchName=*Elantech Touchpad*
AttrTouchpadMultiplier=3
Now, what it recommends for track points was AttrTrackpointMultiplier=0.40 so I assumed that AttrTouchpadMultiplier=3 would work.
It does not. AttrTouchpadMultiplier=3 is not recognized as a usable input.
I have referenced the given list of supported quirks but it seems to be incomplete. It doesn't even have AttrTrackpointMultiplier. https://wayland.freedesktop.org/libinpu … ice-quirks
Further searching has not yielded any results.
Anyone here know where to find a more complete list or at least what I use to change the sensitivity of my trackpad?

Upon an even deeper dive into the code and issues, I found that there is no quirk to adjust the pointer speed. All quirks can be found here. https://gitlab.freedesktop.org/libinput … c/quirks.c
I have also found this github issue. https://gitlab.freedesktop.org/libinput … issues/707
It appears my problem is originating from a bug in libinput itself. For now, it seems I am SOL.
