Xinput - mouse acceleration (none)

I want to set my mouse so that there is no acceleration. I've read that you use xinput and xset. I've (I think...) successfully gotten rid of the acceleration where the gui tools were largely useless...but it's a property that is pretty difficult to "sense" whether or not I've fully turned it off. I made a script to set the values...

//set rival-mouse (10) property (set-prop) acceleration profile (268) to "limited" (7)
xinput set-prop 10 268 7
//set mouse (m) acceleration (0) threshold (0)
xset m 0 0

The mouse does feel pretty good now, but I've also read that it's slightly more complicated than just turning the acceleration off. A few sources say that just turning off acceleration turns off velocity scaling, and that it has an undesirable effect on actually getting the pointer across the screen: it's pixel-by-pixel. My mouse dpi is set very high, around 800, so it's not a problem for me, but what about people with lower-dpi mice? I wish there was a tool that let you set anything you want, while providing a no-acceleration option (or a few varied ones), and had some type of feedback to tell you how the mouse pointer will respond to any settings...maybe a depiction of mouse movement to cursor movement, and a movement curve? And although this might be too much, a dpi setting that could control the dpi setting in the mouse. Not sure if that's possible...

I think that this Is pretty important...with valve pushing gaming on linux, having (any kind of) option for setting up a comfortable configuration for the mouse that's the very best configuration for what you're doing could be a real boon.

Re: Xinput - mouse acceleration (none)

I use, in /etc/X11/xorg.conf.d/50-razer.conf:

Section "InputClass"
    Identifier      "Razer  Razer Abyssus"
    # From lsusb
    MatchUSBID "1532:001c"
    MatchDevicePath "/dev/input/event*"
    Option "GrabDevice" "On"

    Driver "evdev"
    # http://www.x.org/wiki/Development/Documentation/PointerAcceleration
    Option "AccelerationProfile"    "-1"
    Option "ConstantDeceleration"   "3.6"
    Option "AccelVelocityScaling"   "1.0"
    Option "Resolution"             "1800"
    Option "SampleRate"             "1000"
    Option "Emulate3Buttons"        "False"
EndSection

And in the bootloader for cmdline, to mean 1000-times-per-sec polling:

usbhid.mousepoll=1

Re: Xinput - mouse acceleration (none)

Thanks for the response! I'll see if I can adapt that script to my settings/mouse. I'll let you know how it goes.
