UPower not enumerating laptop keyboard LEDs
by nerdinachair from LinuxQuestions.org on (#6E81Q)
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.
