Last update: 26-Jun-2019

Fix Xorg issues:

Open a terminal and type:

$ cd /
$ cd /usr/share/X11/xorg.conf.d/

sudo pluma 910-rat.conf

... and add the following to that file:

Section "InputClass"
Identifier "Saitek Cyborg R.A.T.7 Mouse"
MatchProduct "Saitek Cyborg R.A.T.7 Mouse"
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"
Option "AutoReleaseButtons" "13 14 15"
Option "ZAxisMapping" "4 5 6 7"
EndSection

Save and exit.

$ sudo reboot

Enable mouse polling rate (1000 Hz)

Method one:

Open a terminal and type:

$ cd /
$ cd /etc/modprobe.d/
$ sudo pluma usbhid.conf

... and add the following:

options usbhid mousepoll=1

Save and exit.

$ sudo reboot

Login. Open a terminal and type:

$ cd /
$ cat sys/module/usbhid/parameters/mousepoll

If you see "1", then mouse polling rate (1000 Hz) is enabled.

Method two:

Open a terminal and type:

$ cd /
$ sudo pluma /etc/default/grub

In that file, look for the line that says "GRUB_CMDLINE_LINUX_DEFAULT ="quiet" and add the following:

usbhid.mousepoll=1

The line should look like this:

"GRUB_CMDLINE_LINUX_DEFAULT="usbhid.mousepoll=1 quiet"

Save and exit.

$ sudo update-grub
$ sudo update-grub2
$ sudo reboot

Login. Open a terminal and type:

$ cd /
$ cat sys/module/usbhid/parameters/mousepoll

If you see "1", then mouse polling rate (1000 Hz) is enabled.

Using ratctl utility

Open a terminal and type:

$ wget https://github.com/MayeulC/Saitek/archive/master.zip
$ unzip master.zip
$ cd Saitek-master/
$ sudo cp 90-ratctl.rules etc/udev/rules.d/
$ sudo cp ratctl.py /usr/bin/
$ cd /usr/bin/

And change the owner. Example:

$ sudo chown blackout:blackout ratctl.py

Just change 'blackout:blackout' for your $username

As ratctl utility is written in python, we need some packages or dependencies:

$ sudo apt-get install python3 python3-pyqt5 python3-libusb1
$ sudo udevadm control --reload
$ sudo udevadm trigger
$ ratctl.py

Configure your DPI using the GUI.
