Wireless trackballs for Linux

1 minute read

The Solaar program manages connections with Logitech Unifying receiver on Linux, including pairing/unpairing. This means wireless keyboards and mice, including wireless trackballs work well on Linux. Logitech wireless firmware updates are provided seamlessly in Linux. The Unifying receiver “just works” on Linux upon plugging in, with trackballs being recognized as an HID device.

I choose a trackball as I often have a busy desk without room for mice, and want to avoid strain on my wrist.

Logitech M570

The Logitech M570 has been around since 2010. The price has dropped from $60 to $25. The M570 is a user-maintainable trackball with back/forward buttons and clickable roller for programming and web-browsing convenience. I have multiple Logitech M570’s, and they have proved durable on the road and during heavy usage.

Cleaning

I spilled soda into my M570, and readily was able to take the M570 apart with a jeweler’s Phillips screwdriver and clean it. Every few months, you can pop out the trackball and clean the rollers or just blow on them to get the dust out.

Logitech MX Ergo

The $100 MX Ergo was released in 2017, and uses the Unifying receiver OR Bluetooth Low Energy. The MX Ergo also works through Solaar on Linux.
