Darter pro keyboard backlight control broken after latest update

[bwat47]

After getting the latest update to system76-dkms (1.0.5~1565016960~19.04~95bffee), the keyboard backlight hotkeys no longer work.

The backlight is stuck on (and with a blue color) no matter what

Ubuntu 19.04 Darter pro (darp5)

The behavior is the same as this prior issue that was fixed in april: https://github.com/pop-os/system76-dkms/pull/23

Thanks, I will make sure there hasn't been a regression in a couple hours

It looks like the same mistake was made again - not sure why I keep thinking it has the same keyboard backlight as the Galago Pro. It will be fixed soon.

It is fixed in system76-dkms 1.0.6

I normally have my backlight off, but doing an early morning start I was trying to turn mine on and then found this issue. Is this a reoccurring thing?

Here are my specs and I am running a darter pro darp6

@mebays Are you using proprietary EC? You are probably experiencing https://github.com/pop-os/system76-acpi-dkms/issues/15.

You can switch to Open EC if you don't have a reason to require proprietary EC, or watch that issue for updates.

Using that link I'm using Open Firmware. Went ahead and followed those directions though and looks like it's working now after reboot. So thanks for the link!

Just to clarify, Open Firmware does not imply Open EC. "Open Firmware" refers to UEFI firmware/coreboot, while "Open EC" refers to EC firmware. darp6 shipped with Open Firmware but proprietary EC. It sounds like you successfully transitioned to Open EC. Glad to hear it's working!

Thanks Jacob! After hours of searching, this worked
