X11_Mouse/Change_Mouse_Resolution

Introduction

Increasing your mouse polling rate is a common tweak which many gamers perform on their systems. This article will describe the method of setting your mouse's polling rate.

lomoco

lomoco (Logitech Mouse Control) can change the CPI resolutions on some Logitech mice. To change cpi resolution for Logitech mice, install the package:

emerge --ask --verbose lomoco

The run lomoco -8 to change the resolution to 800cpi.

If you want to make the change permantly, create the following file:

BUS=="usb", SYSFS{manufacturer}=="Logitech", SYSFS{product}=="USB-PS/2 Optical Mouse", RUN+="/usr/bin/lomoco -8"

USB HID driver

The usbhid driver provides a method to change the polling interval. The mousepoll argument accepts an integer, the interval between mouse polls in milliseconds:

• 1 = 1000Hz
• 2 = 500Hz
• 4 = 250Hz
• 8 = 125Hz
• 10 = 100Hz (Default)

• If you build the USB Human Interface Device (full HID) support driver into the kernel, append usbhid.mousepoll=Your polling interval to the kernel line of your boot manger config, e.g. /boot/grub/grub.conf with 500Hz interval:

kernel other_kernel_options usbhid.mousepoll=2

• If you build the USB Human Interface Device (full HID) support driver as modules, add the following to /etc/modprobe.d/usbhid, e.g. with 500Hz interval:

 options usbhid mousepoll=2
 

Afterwards run update-modules.
