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) :

Formation en sécurité : mise-à-jour pour recommander KeepassXC

J’ai fait une mise-à-jour importante au matériel du cours de sécurité numérique que j’avais conçu il y a 2 ans pour l’École de sécurité numérique.

J’ai remplacé la section de gestion de mots de passe pour y faire une recommandation unique sur le logiciel KeepassXC, qui est disponible nativement sur GNU/Linux, macOS et Windows. Il est aussi possible de l’intégrer à son navigateur, c’est un gros progrès par rapport au premières version de Keepass!
