Issue/Bug Description:

I have an Oryx Pro 3. This package suddenly began controlling the keyboard backlight brightness and color scheme a while back. Now, it has completely ceased working, resulting in an always on, white backlight.

Steps to reproduce (if you know):

Expected behavior: Keyboard Backlight hotkeys become useful during the beginning of the boot process and remains useful during system operation.

Other Notes: I reinstalled Pop_OS! and Ubuntu LTS several times to see if it was a configuration issue. Nothing has yet helped.

@KinshipCourier can you try to reinstall the firmware by running sudo system76-firmware and clicking on Reinstall Firmware?

ghost commented 5 years ago

@jackpot51 Alrighty, I just reflashed the firmware successfully , but there's been no change with the keyboard backlight. I've upgraded the kernel to 4.17 branch and that didn't either. 4.18 kept throwing DKMS errors.

The firmware version is BIOS: 1.05.03RSA1 EC: 1.05.03MI2 EC2: N/A ME 11.6.10.1196

I noticed that the red LED that illuminated the headphone jack socket is no longer on, too. It does flicker just before the boot process finishes and the desktop appears. I don't know if that helps any.

Also, just to be clear the keyboard backlight no longer shows up in the power menu either. The title seemed a bit ambiguous to that point.

I just ran lm-sensors in the terminal and noticed that the fan speeds are no longer displayed under the "system76" section at the end of the printout. I also went back to the standard kernel after I saw there was an update, applied several updates from system76-power and system76-driver(and -nvidia), went back to the 4.17 kernel and now the red LED in the headphone jack is working again.

I don't know if any of this is helping you, but I'll keep looking for changes.

I found that turning off the machine and then unplugging the power adapter reverts the backlight to firmware control.

Woah, that worked! Awesome, thank you for your help! I would never have thought of that.

Glad to hear it

Same here, and same here. Still no idea why unplugging the adapter has anything to do with that. But it worked! Thank you!

@jackpot51 This hint was somehow hard to find. I assume there are more Oryx Pro 3 owners out there with the same issue. Maybe it would be worth considering to put it on the System76 support page? At least that's where I started to look for a solution.
