Change DPI of Logitech Mouse

Question

Okay so as the title says I want to be able to change my DPI in my Logitech G400 mouse to be exact. Is there any way of doing this?

Solution

Install solaar and see if their DPI settings apply to the G400.

See http://pwr.github.io/Solaar/ for more information about solaar.

Add deb http://ppa.launchpad.net/trebelnik-stefina/solaar/ubuntu yakkety main repository if you don't find solaar in the Ubuntu repositories.

• note: if you're using a Ubuntu newer than yakkety, you may have to manually change the Ubuntu version in Software & Updates, as yakkety was the latest repository for solaar.

To add the PPA, in terminal...

sudo add-apt-repository ppa:trebelnik-stefina/solaar

To install, in terminal...

sudo apt-get update
sudo apt-get install solaar

Then pair the G400, and once paired, open the G400 settings and check/adjust the DPI.

Solaar doesn't seem to apply for the Logitech G400 device unfortunately. It says No Logitech receiver found. I have however found another way to change the DPI and the samping rate for the Logitech G400. If anyone is interested in it they can read more about it here https://github.com/rprichard/logitech-g400-config

@blazefantasyy it didn't find the Logitech receiver either because it's not a unifying receiver, or it needs the firmware update, or you need to plug it directly into a computer USB port, or you just need to unplug/reinsert it.

I'm guessing it's not a unifying receiver then as I have it plugged directly into a computer USB pot and have attempted to unplug and then plug it in again. Also I don't think theres any way to firmware update it if I'm on linux.

@blazefantasyy You paired the G400 with the Logitech Dongle in Windows, yes? If so, that's where to do the firmware update.

If you're asking if I have Logitech Gaming Software on Windows then yes, I do.

@blazefantasyy no, ultimately I was saying that you do the firmware update from Windows. Just like right now you have to pair the mouse with the Logitech receiver in Windows. Solaar is a Linux version of the Logitech software functionality. See community.logitech.com/s/question/0D531000055gw8YCAQ/…
