mainline VS Solaar

See also https://github.com/bkw777/mainline which offers a UI to install the mainline kernels from mainline kernels PPA.

You are referring to this, right? https://github.com/bkw777/mainline

use the Mainline Tool to install the latest kernel: https://github.com/bkw777/mainline

on Ubuntu or derivates of it like Linux Mint just use https://github.com/bkw777/mainline which pulls newer updates automatically

Lastly, of you want to play with kernels, install mainline.....https://github.com/bkw777/mainline

On Mint 21? I don't think so. The only possible way would be to install Mint 20.3 which comes with the older Cinnamon before the Mutter rebase. You could then install a newer kernel like 6.3 using Mainline, but you would be stuck with an Ubuntu 20.04 base which means much older apps in the repositories.

Out of the box Ubuntu and derivatives (and also Debian upstream of Ubuntu) are probably shipping with older kernels. Normally I'd just suggest installing the GUI kernel version management tool mainline (IIRC mainline should just be available in the Ubuntu software center) and just installing a more recent kernel to get support. Though you indicated you didn't want to touch the command line, it is also very possible to load drivers that are not shipped with the kernel if someone were willing to do so.

If it's got the Logitech unifying receiver, it won't work outta the box. You gotta download Solaar

- Solaar: Device manager for Logitech devices (connected via Unifying, Bolt, Lightspeed or Nano receivers + some connected via USB cable / Bluetooth)

Depending on your mouse, Solaar could do the job. I use it in combination to trigger Fly-Pie.

Now moving on to the Linux part. Do you use gnome/kde? Or some tiling DE? I use Solaar and it's lovely! M720 has a perfectly placed gestures button. I use it to move my windows to left/right monitors and switch between upper/lower desktop spaces. The gesture button works flawlessly when you set up solaar correctly.

I've been beating my head against the wall trying to figure out why this isn't working as I expect. I'm trying to make a user service to run solaar so that my logitech mouse's scroll wheel behaves like I want without having to open the app manually. The software itself provides a .desktop file for autostart, and I used this as a basis.

I've used Solaar for my MX Master 3, works great. https://pwr-solaar.github.io/Solaar/

We don't officially support wireless keyboards or mice for infosec, environmental, and supportability reasons. But if we had to, the established Logitech Unifying and newer Logitech Bolt ecosystem allow for ready re-pairing of dongles with peripherals. Logitech Unifying is fully functional under Linux with solaar from your distro's repos. You have to be astute when buying, to always look for a picture of the dongle with the orange Unifying logo or the safety-yellow Bolt logo, however. If the logo isn't on the packaging or in the promo picture, I can assure you that you will not get a Unifying or Bolt dongle.

Have you tried Solaar?
