Delux M618 / J-Tech Digital scroll endurance : an affordable ergonomic wireless vertical mouse that just works in GNU/Linux

The Delux M618 or M618GX ergonomic vertical mouse is a very simple, comfortable yet affordable wireless device that just works with GNU/Linux (I used Debian and Ubuntu), as expected.

While improving my work-at-home setup I upgraded to an ergonomic vertical mouse following a recommendation from a colleague that specializes in office ergonomics.

It’s taken a couple of weeks to adjust to it but I love it ! I am considering buying another to bring with me when leaving home and working elsewhere. Even if it’s a bit bigger than a regular mouse, I think it’s worth it.

The battery life is good (still running after 3 months), the small USB receiver is not compatible with anything else but that was expected. It’s sitting permanently on a KVM to be shared with other systems so I don’t mind.


Features :

  • Special curve backside, thumb groove, delicate buttons layout and anti-skid rubber coasting
  • 2.4 GHz wireless connectivity
  • On/Off button, 2 AAA batteries required
  • 6 Buttons, including a button to adjust DPI (800/1000/1600)
  • Removable Wrist Rest

This mouse is also sold under the J-Tech Digital scroll endurance brand.

Button mapping

There’s nothing special to do regarding buttton mapping. Here is the detailed information about each button functionality as expected in Windows – it matches the behavior in GNU/Linux (I use Debian and Ubuntu) :

Pairing the Logitech Performance MX (and others) to the Unifying Receiver in GNU/Linux

Back in 2009 Logitech introduced the Unifying Receiver, a great way to connect multiple wireless mice and keyboards to one single RF receiver on your PC.

The Unifying receiver is uniquely paired to your mice and keyboard. When you buy your devices, they are already paired to the accompanying receiver. They work out of the box on any GNU/Linux system.

However, if you loose the original receiver, and get another one for free from Logitech under warranty, or if you want to pair / unpair new or existing devices, you will need to pair them again. This used to be only possible using Windows. Not anymore. 🙂

Solaar is a GNU/Linux device manager for Logitech’s Unifying Receiver peripherals. It is able to pair/unpair devices to the receiver, and for most devices read battery status.

It comes in two flavors, command-line and GUI. Both are able to list the devices paired to a Unifying Receiver, show detailed info for each device, and also pair/unpair supported devices with the receiver.

I tested this in Debian 7 for which there are packages and a repository, and there is also a PPA available for Ubuntu, which also works in Trisquel 6. Here are some screenshots:





Wow, it’s been quite some time I hadn’t seen such attention to detail in an application apparently destined to such a « simple » task.

Buttons mapping

Solaar doesn’t take care of the buttons mapping (yet?), but I thought I’d throw this extra here. Some time ago I went through the trouble of identifying all the buttons on my mouse and documenting (from Logitech’s accompanying manual) the various expected functions as present in Windows.

This is useful for applications where you can specify which button is assigned to an action. Enjoy!
