Hey all,

This is one of those issues that obviously isn't a blocker, it just bugs me that it works correctly in Fedora for me but not in my current Arch setup. It's an Asus laptop, and I have Asusctl set up and working so I'm able to use that to make the keyboard LEDs work statically. However, in Fedora with KDE there is a slider in the power panel that is for the keyboard LEDs and that is missing in Arch with KDE. The only reason that matters is I'd like the keyboard LEDs to turn off when the monitors go into standby which was the behavior in Fedora. I'm assuming the keyboard LED slider being missing in KDE is a symptom of this issue so I did my research and found that the power panel uses the UPower daemon to enumerate available power devices and it would appear it is not seeing the laptop keyboard. I found multiple posts pointing to a disabling a setting named ProtectKernelTunables and did so but it didn't fix the issue like it did for others. I thought I'd see if anyone has any insights.

How about:

Hey Tekk!

I had already consulted this wiki article and it would contain solutions if my issue was that I was unable to control keyboard LEDs at all. This is not the case because the Asusctl package allows me to issue command line calls to adjust brightness and has config files for color. The issue I'm having is that the power daemon doesn't see the keyboard LEDs and so does not turn them off when the monitor is put to sleep. Different issue, though thank you for the response.

This issue turned out to be caused by enabling the intel thermald daemon. No idea why enabling it takes away the keyboard LED functionality in the powerdevil panel in KDE. But that is what I managed to trace it to.
