`libinput` upgrade causes mouse sensitivity to go unreasonably high

Issues & Assistance
1

After upgrading my system and rebooting I noticed that my pointer was incredibly fast. Nothing in the settings has changed. After checking the upgrade logs I noted that xf86-input-libinput was upgraded from 1.2.1-1 to 1.3.0-1. Commit history mentioned adding a new mouse acceleration profile, so I tried manually setting the flat profile with xinput set-prop 8 298 0 1 0. The default after logging in is 1 0 0. This reverted the behavior, but that fix does not persist across reboots. Changing the acceleration profile in the KDE system settings does not do anything, the pointer speed doesn't change, nor is prop 298 updated. Is this something I can fix on my own or do I need to wait for someone upstream?

Maybe you could check the bugs.kde.org for something similar.
If changing a setting in Plasma's own panel doesn't do anything, the first place I would go for is bugs.kde.org.
Googling might also come up with results as sometimes old issues may rehappen, although I have no idea if this one even happened.

How interesting... 468217 – xf86-input-libinput 1.3.0 DPI and mouse acceleration issue on KDE Plasma X11

Making the Changes Persistent

The method explained above changes settings for active session only. When you reboot the system, these changes will be gone. To make them persistent, two approaches can be used.

The first method requires you to add these commands to startup applications. ...

Good to know it's already been reported. Guess I'll just stick to manual workarounds until someone at KDE fixes it. Or I get tired and create a config file.

  1. Downgrade x86-input-libinput
  2. Place a HoldPkg IgnorePkg x86-input-libinput in /etc/pacman.conf
    :question: :question: :question:

EDIT: Corrected. Thanks! :slight_smile:

I think it's IgnorePkg?

Yes, I am sure he meant IgnorePkg. HoldPkg would not be useful in this case.

HoldPkg = package …

If a user tries to --remove a package that’s listed in HoldPkg, pacman will ask for confirmation before proceeding. Shell-style glob patterns are allowed.

IgnorePkg = package …

Instructs pacman to ignore any upgrades for this package when performing a --sysupgrade. Shell-style glob patterns are allowed.

I think it is a good suggestion though: downgrade the package and add it to IgnorePkg. Check on it again in a couple weeks.

...
IgnorePkg = xf86-input-libinput

@adamski234 The bug is now in RESOLVED FIXED and will be part of 5.27.5.

Mouse acceleration profiles now work properly when using Libinput 1.3 or later (Ilia Kats, Plasma 5.27.5. Link)

I will close this.

Fixed by KDE dev. YEAH! :smiley:
