> I just don't understand it. Because we don't know how to use the feature yet. But you can connect something like a CPU trigger to a led, so use 3 keys with 3 colors for CPU%, RAM%, SWAP%, then one blinking for disk IO, network IO and you get something very useful!! For a full keyboard, you could have predictive input for the other as a typing assistant (ex: after pressing t,y put r in a strong green, e in a lighter…
I also find CPU/RAM monitoring not very useful to me. I used to put conky widgets all over the place, but concluded that it did very little. Most of the time I fire up htop, I'm looking to kill a process anyway. I programmed one of my keyboard to be modal, and use the lighting as an indicator of which mode I'm in. Sort of like vim's status bar. It's pretty handy.
Exactly this! I don't want to waste screen space or CPU time to fancy widgets, but having a few leds that blink too much when my system does too many things is very handy. It's like in the old days of HDD leds: it didn't intrude, but I quickly knew what was going on if I looked at it. And blinking things have a tendency to catch your attention, so it removes the "monitoring" problem too (because, when do you know it's time to check htop?)
Linux LED triggers are very handy to do just than.
