MCHOSEProfileSwitcher

These scripts, written in Python and automated with Selenium, automatically apply a performance profile (including motion sync, polling rate, DPI, etc.) when launching a Steam game on Linux, and switch to a power-saving profile when closing it.

Instructions

Install chromium, python and python-selenium:

yay -S chromium python python-selenium

Get the Vendor ID and Product ID of your mouse from:

lsusb

Create an udev rule:

nano /etc/udev/rules.d/99-mouse-mchose.rules

Paste the following line into the file, making sure to change your specific mouse Vendor ID and Product ID in the appropriate fields:

KERNEL=="hidraw*", ATTRS{idVendor}=="3837", ATTRS{idProduct}=="100b", MODE="0666", TAG+="uaccess"

Reload udev rules:

udevadm control --reload && udevadm trigger

Start Chromium from the terminal in the specified user directory:

chromium --user-data-dir=$HOME/.config/chromium_profile

Open the MCHOSE webdriver website, pair your mouse and create two profiles, one called "Performance" and one called "Powersave":

www.mchose.com.cn

Copy the URL you see in the address bar for your mouse and edit it in your scripts (example from MCHOSE A7 V2 ULTRA):

URL = "https://www.mchose.com.cn/#/detail?deviceName=MCHOSE+A7+V2+Ultra"

Add to Steam Game Commands (change the directory based on where your scripts are):

python3 ~/Scripts/mouse.py Performance %command%; python3 ~/Scripts/mouse.py Powersave
