Xinput and mouse deceleration dude


I want to reduce mouse pointer speed. So...

xinput list
xinput list-props deviceID (Appear Device Accel Constant Deceleration)
xinput set-prop deviceID deviceaccelconstantdecelerationID 5.0


Before update to current I could do it. But now not work.

When I type "xinput list-props deviceID" appear this...

With deviceID=11:

Thanks.

Have you checked KDE's system settings?
https://userbase.kde.org/System_Sett..._Devices#Mouse

The options to put in xorg.conf are found here:
man xorg.conf
https://wiki.archlinux.org/index.php/Mouse_acceleration

Question about xinput and libinput after system update

man xorg.conf
https://wiki.archlinux.org/index.php/Mouse_acceleration
I did this and decrease the pointer speed:

Quote:
/etc/X11/xorg.conf.d/50-mouse-acceleration.conf

Section "InputClass"
Identifier "My Mouse"
MatchIsPointer "yes"
Option "AccelerationProfile" "-1"
Option "AccelerationScheme" "none"
Option "AccelSpeed" "-1"
EndSection

My question is: Why change the xinput result after system update.

Xinput structure before update, similar to:

Quote:
Device 'mouse brand':
Device Enabled (121): 1
Device Accel Profile (240): 0
Device Accel Constant Deceleration (241): 1.000000
Device Accel Adaptive Deceleration (243): 1.000000
Device Accel Velocity Scaling (244): 10.000000
Xinput structure after update, similar to:

Quote:
Device 'Razer Razer DeathAdder Elite':
Device Enabled (152): 1
Coordinate Transformation Matrix (154): 1.000000, 0.000000, 0.000000, 0.000000, 1.000000, 0.000000, 0.000000, 0.000000, 1.000000
libinput Natural Scrolling Enabled (287): 0
