With a basic Logitech gaming mouse from a few years ago, it had the simple default RGB effects at all times, Windows, Linux, even DOS.

Recently on Windows 11 there was a firmware update from Logitech and now the RGB is controllable from W11 built-in FX interface.

But no more RGB at all when you reboot to Linux ever since.

I thought that was going to last forever, guess I was wrong.

Turned out to be quite a dark mouse most of the time.
