I need to try that. Mine is USB wired with no battery.
I've got one of the lesser G USB 6-button "gaming" RGBs that was unused for well over a year. Never did try any Logi Windows apps or do any gaming either. Used as a mild-mannered office mouse instead :)
A while back I started using it again, this time on a Linux PC and it still glowed with the default pattern which I had never changed. Fine by me.
Then started dual booting Windows 11 and all was well until I connected to the internet, the Logitech firmware on the mouse got autoupdated, and lights out :(
Still glows during POST but LEDs go out unless Windows kicks it back on in some way or another.
You want it to do what it once was doing without an app? Your Windows 11 may already be updated far enough itself to give RGB control now.
Otherwise you can use the Logitech app.
Which doesn't have a Linux version.
Looks like mine needs a background app of some kind now if I want glowing again. Oh well.
Still looking forward to trying Solaar when I get back to that particular desktop :)
My first one was a g9x, followed by a g700s. Those may look a bit "gamery", but I later had a g703 which was as sober as they come.
And, even though it's not as critical for office use, I found it very pleasant to have next to no lag on a wireless mouse. I now have a mx master 3s, which has "ok" wireless performance and is surprisingly nimble for its size and weight. I can't complain about it while I use it, but I immediately feel the difference when I switch to a Logitech G Lightspeed or a friend's Razer with whatever their equivalent technology is called.
And since these aren't that expensive (the MX is actually the most expensive mouse I've ever had), this tends to reinforce my considering them as full competitors to logi's "office" line.
