Expected behavior: Black light control to work from keyboard hotkeys.

This issue only affects proprietary EC and does not affect Open EC; darp6 users should transition to Open EC if possible. galp4 does not have Open EC released, however.

darp6 user here. How does one transition to Open EC..if possible? I fixed this issue a by simply removing the call to get the "NFAN" and "NTMP" objects.

thomas-zimmerman commented 2 years ago

For darp6 users, you should be able to transition to the Open EC with the following commands:

sudo apt update && sudo apt install system76-firmware
sudo system76-firmware-cli schedule --open

This assumes that you are running Pop!OS or Ubuntu with the System76 PPA enabled.

Thanks. I love my darp6 Hate it with things don't work

Thanks for the pointer @thomas-zimmerman. I have a darp6 impacted by this issue, and transitioning to the Open EC (per your commands), has not resolved this issue. Has the Open EC fix been released @jacobgkau?

jacobgkau commented 2 years ago

@smugcloud Yes, Open EC was released for darp6 in September 2020. Can you please provide the output of sudo dmidecode in a text file to confirm your current version?

Thanks @jacobgkau. Of course, as soon as I wake my machine, the back light is working (when it was not after the firmware install).

Here is the output regardless. Thanks for the help! backlight.txt

2021-07-20_93c2809 is the correct version for Open EC. Glad to hear it's working.
