Logitech G25 Racing Wheel

Question

How can I set up a Logitech G25 Racing Wheel in Ubuntu 12.04?

Is there a driver or other tool avaiable?

I'll be using it in Speed Dreams.

Answer 1

You can use LTWheelConf to change various settings of the Logitech racing wheels

• Driving Force
• Momo Racing
• Momo Force
• Driving Force Pro
• Driving Force GT
• G25
• G27

Available options:

• set wheel to "native" mode (support separate axes and clutch pedal, H shifter, full 900 degree rotation)
• Set wheel rotation range
• Set autocenter force and rampspeed
• Set ForceFeedback gain

Compile and install

You can easily compile LTWheelConf using the following commands:

Get some dependencies

sudo apt-get install libusb-1.0-0-dev git

Download the source

git clone https://github.com/thk/LTWheelConf.git

Build the source

cd LTWheelConf
make

Install

cp ltwheelconf /usr/local/bin/

You should now have an executable named ltwheelconf.

List all found/supported devices

sudo ltwheelconf --list

Supported wheel shortname values:

• 'DF' (Driving Force)
• 'MR' (Momo Racing)
• 'MF' (Momo Force)
• 'DFP' (Driving Force Pro)
• 'DFGT' (Driving Force GT)
• 'G25' (G25) <-- This is, obviously, the shortname of your steering wheel
• 'G27' (G27)

Set wheel to native mode

sudo ltwheelconf --wheel <your-wheel-shortname> --nativemode

Set wheel rotation range of 900 degrees

sudo ltwheelconf --wheel <your-wheel-shortname> --range 900  

Examples:

Put wheel into native mode:

$ sudo ltwheelconf --wheel G25 --nativemode

Set wheel rotation range to 540 degree:

$ sudo ltwheelconf --wheel G25 --range 540

Set moderate autocenter:

$ sudo ltwheelconf --wheel G25 --autocenter 100 --rampspeed 1

Disable autocenter completely:

$ sudo ltwheelconf --wheel G25 --autocenter 0 --rampspeed 0

Set native mode, disable autocenter and set wheel rotation range of 900 degrees in one call:

$ sudo ltwheelconf --wheel G25 --nativemode --range 900 --autocenter 0 --rampspeed 0

To test and calibrate the steering wheel you can use jstest-gtk

Add UDEV rule

It is possible to add a rule to UDEV to automatically invoke LTWheelConf when the steering wheel is connected.

This can be done using the following command (use the correct shortname instead of <your-wheel-shortname>!):

echo 'ATTRS{idVendor}=="046d", ATTRS{idProduct}=="c294", RUN+="/usr/local/bin/ltwheelconf --wheel <your-wheel-shortname> --nativemode --range 900"' | sudo tee -a /etc/udev/rules.d/90-logitech-wheel.rules

Now you need to restart UDEV:

sudo service udev restart
