I recently purchased the MX Master 4, and it was easy to remap the gesture buttons and configure features like SmartShift and high-resolution scrolling.

I use this to manage my unifying receiver. I don't think I have touched it once in years, just works.

Agreed. I found it so avoided having to install the Logitech spyware anywhere. I won't make that mistake twice.

Another vote here. MX keys and mouse and Linux Mint. Love it, set up once and have never touched it since.

Does anybody know if there is a way to remap the "gesture button" (thumb) to launch a .sh ? I've tried a dozen way without success, the only thing I can do is map the .sh to an actual gesture (button+scroll up) but I don't want to use gestures !

Came for this, I use it a lot as someone who has a ton of rando different logitech things.

One deal that I haven't dived into -- what is up with the ones that appear to limit how many times you can change devices? Is that real and not hackable?

Neither really worked for me on fedora. Ratbag can't see the mx master 3s and solar couldn't remap anything.

Did you install the Solaar udev rules?

+1 for Solaar! Logitech should give them money because I would not buy Logitech without Solaar (I'm on Linux exclusively with an MX Master 3S and an MX Keys Keyboard... Crazily each with their own dongle :facepalm:

(Unifying receiver does not unify unifying and bolt so not so unifying eh! Oh and bolt is newer but not backwards compatible, so annoying!))
