Lots of modern desktop PCs have case LED's that could easily find use as system activity indicators if the Linux kernel (or userspace HAL) supported them. Unfortunately support seems to be really patchy.
- deadbunny 8y agoI believe there is some work on standardizing the RGB LED interface going on as we speak: https://lkml.org/lkml/2019/1/5/191 https://lkml.org/lkml/2019/1/5/191
- pantalaimon 8y agoLinux already has an LED interface, it's just that currently you can give an LED a brightness value 0-255. So a RGB LED would have to be represented by three entries in /sys/class/leds/ That's kind of inconvenient when those three LEDs are actually one RGB LED. This is only how the LEDs are represented to user space, you still need a driver for the chips the LEDs are connected to.
