[SOLVED] Disabling mouse acceleration

Hello everyone. I really want to disable acceleration on my mouse, but for some reason I just can't get it to work. If anyone has any idea of what to try or have had a similar problem, that would be really helpful. I have tried all of the following.

1. xset
Running

xset m 1/1 0

or putting it in my .xinitrc seems to have no effect. Interestingly, neither does calling xset with any other values (like "5/1 0", which I think should add a lot of mouse acceleration). Before switching to Arch, I used Gentoo, where this worked just fine.

2. Xorg configuration
I created /etc/X11/xorg.conf.d/50-mouse-acceleration.conf and tried putting both

Identifier "Mouse"
	MatchIsPointer "yes"
	Option "AccelerationNumerator" "1"
	Option "AccelerationDenominator" "1"
	Option "AccelerationThreshold" "0"
EndSection

and

Identifier "Mouse"
	MatchIsPointer "yes"
	Option "AccelerationProfile" "-1"
	Option "AccelerationScheme" "none"
EndSection

in the file (not at the same time), as described on the wiki. Each time I restarted X, but it had no effect.

3. xinput
I found this thread, in which someone suggest running "xinput set-prop 8 'Device Accel Profile' -1" where 8 is the id of the device with the "Device Accel Profile" property. The output from "xinput list" is this:

⎡ Virtual core pointer                    	id=2	[master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer              	id=4	[slave  pointer  (2)]
⎜   ↳ SteelSeries Sensei Raw Gaming Mouse     	id=8	[slave  pointer  (2)]
⎜   ↳ SteelSeries Sensei Raw Gaming Mouse     	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)]
    ↳ Power Button                            	id=7	[slave  keyboard (3)]
    ↳ SteelSeries Sensei Raw Gaming Mouse     	id=9	[slave  keyboard (3)]
    ↳ AT Translated Set 2 keyboard            	id=11	[slave  keyboard (3)]

If I'm reading this output correctly, ids 2, 4, 8, and 10 are mice, but none of them seem to have the "Device Accel Profile" property:

$ xinput list-props 2 4 8 10

	libinput Send Events Mode Enabled Default (266):	0, 0
	Device Node (267):	"/dev/input/event3"
	Device Product ID (268):	4152, 4969

As you can see in the output above, my mouse is a SteelSeries Sensei Raw (just one!). Unfortunately I don't have any other mice to test with.

Re: [SOLVED] Disabling mouse acceleration

Please post the output of

xset -q | grep -A1 Pointer

Re: [SOLVED] Disabling mouse acceleration

Running that gives me:

$ xset -q | grep -A1 Pointer
Pointer Control:
  acceleration:  1/1    threshold:  0

See previous thread.

Thanks! I can't believe I didn't find that.

You didn't actually need to remove libinput to remove acceleration, as it can be disabled with libinput too. As I've written in the other thread:

Section "InputClass"
        Identifier "My Mouse"
        MatchIsPointer "yes"
        Option "AccelSpeed" "-1"
EndSection

Re: [SOLVED] Disabling mouse acceleration

Well, there's a libinput bug report re acceleration - it ain't fully disabling acceleration.

Comment #3 is the most informative in that bug report. And comment #4 is the most amusing
