Madcatz Rat7 stops working intermittently in Linux Mint

This method works for sure for Linux Mint

sudo mkdir /etc/X11/xorg.conf.d

sudo vi /etc/X11/xorg.conf.d/910-rat.conf

File includes:


Section "InputClass"

Identifier "R.A.T."

MatchProduct "R.A.T.7|R.A.T.9"

MatchDevicePath "/dev/input/event*"

Option "Buttons" "17"

Option "ButtonMapping" "1 2 3 4 5 0 0 8 9 7 6 12 0 0 0 16 17"

sudo apt-get update

sudo apt-get upgrade

reboot

Someone else suggested a simpler configuration and I have tried it.  It works fine.

MOUSE SETTING

As for the single left click registered as a double click, there is a small middle button to control the speed of the mouse movement, click backward until the red light on the left side has only one lit bar

Also in combination with the mouse and trackpad setting: turn down the sensitivity of the double-click.

And the double-click timeout setting to very long.

It is still not perfect but tolerable.
