High DPI mouse too fast

[smithxi]

my 2000 dpi mouse on the lowest settings in mouse control is too fast, is there any way i can modify anything to make it slower?

lmao i had the same problem.. assuming your in gnome, click on (top left panel) system -> preferences -> mouse -> (tab) motion

[smithxi]

see thats what i mean, the lowest settings in there aren't even slow enough for me.

hmm... i think there is some x configureation file to mess with.. but im not 100% how to change them correctly, so i cannot help you.. sorry!

someone in IRC chat suggested xset m X X, and that worked for changing it, but even really low numbers didn't lower it enough. there has to be some method of changing the dpi. also i'd like to be able to set the scroll speed to 1 line.

did you fix it? I get the same problem with my razer deathadder black.....it is 3500DPI LOL

What happens if you configure the windows driver to 450 dpi and then reboot to Linux?

For a 3500DPI mouse, try slowing it down by a factor of 4 by creating a file called /etc/X11/xorg.conf.d/30-mymouse.conf with these contents:

Section "InputClass"
   Identifier "My mouse"
   MatchIsPointer "true"
   Option "ConstantDeceleration" "4"
EndSection

You'll have to restart X for it to take effect. You can find more info about mouse acceleration in the xorg.conf man page.

I run this script in my .xinitrc to reduce the cursor speed for my 3600 dpi mouse:

#!/bin/sh

for i in `xinput list|grep "4Tech USB Full Speed"|cut -d "=" -f 2|cut -d "      " -f 1`; do
        xinput set-float-prop $i 'Device Accel Constant Deceleration' 2.5;
done

Replace "4Tech USB Full Speed" with your device name (run xinput list).

Doing it like this has the advantage that other mice that get connected (or touchpads) aren't affected.
