I recently purchased 2 Logitech MX Anywhere and 2 Logitech MX Performance mice as replacements for my Logitech Trackman Marble. The Anywhere mouse is ambidextrous for the most part, which is why I purchased it in addition to the Performance mouse. The Anywhere mouse will allow me to switch to my left hand in an effort to stave off RSI-related hand issues.
So, I was wondering if there was any software available for Linux for Logitech products. Turns out there are a few packages under Debian. I found one in particular that caught my eye;
solaar. Solaar enables you to pair a Logitech unifying device with the unifying receiver, which is a very small USB dongle. Solaar can also provide a battery status icon, which sits in the tray area, for some Logitech unifying devices.
The battery status icon for the mouse is on the far left in the screenshot below.
