Hello,
I have tested LED triggers (/sys/class/leds/_led_id_/trigger) on two different machines. The results in my case are:
kbd-* don't work unless they're enabled on keyboard LED device
power-related AC-*, BAT0 don't work
disk-* works only with a SATA drive, but not with USB flash (UAS), MMC, NVMe
cpu* don't work, but if I load ledtrig_activity module and use its trigger, then it works
audio-* don't work. Tried muting with ALSA & PulseAudio
phy0rx, phy0tx make the LED blink, but blinking is not correlated with transmitting / receiving data
Others work or I was unable to test them. Any idea why I see this behaviour and how to make those triggers work?
