Customize keyboard backlight

Is it possible to customize features of the keyboard & backlight? Example are:

  • changing backlight timeout (for battery and plugged in)
  • scheduling backlight (enable during nighttime & on battery)
  • toggle when screen brightness is low
  • toggle backlight for certain keys (and add cool effects)
  • changing what function keys do
  • customize power button backlight

I’d second this. The change of kbd backlight levels is something that I got really used to and would be nice to have.

This is handled by the EC(embedded controller) which is open source, at the moment this functionality is not well exposed to the user but it should be technically do able but I’m not sure how

Framework is planning on making this easier to tweak in the future I believe

I’d like to see this as well.

One thing I miss from my Thinkpad is a led for mute status. If I could turn on the backlight for just the F1 key to indicate “muted”, that could be cool.

That’d also be useful. WhyTF does Fn+F9 fake like typing Meta+P instead of producing a proper scancode? (Yeah, I know, the answer is some Windows stupidity, that’s not the point)

+1 for timeout. One of the remaining things I envy on my partner’s macbook.

I’d just like to second this request. Just something I could modify in /sys/class/leds/ or something

Is there any update on this feature request? This is my main “bug” with the Framework right now. It’s also been talked about here.

I’m ok with 3rd party software (Windows) if that would be available.

Still waiting for the keyboard backlight timeout to be “fixed”. :frowning:

I’m working on a VERY simple program that does a keyboard backlight timeout using the ectool on Gnome systems (it uses Gnome’s dbus and Mutter to know when the user is idle). I’d like to share it, but it needs some configuration of dbus to work in a way that I think might be insecure.

I just wrote a small Linux daemon to do this GitHub - jonas-schievink/keylightd: Keyboard backlight daemon for the Framework Laptop

No fancy features, just “turn backlight on when keyboard or touchpad are used” and “turn it back off after a timeout”, since that’s what I was missing from my XPS 13.

(it uses evdev directly, so doesn’t need any specific desktop environment)

@jschievink This is great. I also ended up working on an ioctl based version (was also done in rust) but yours is better!

I had this Daemon installed on my 12th gen Intel framework 13, worked like a charm and loved it.
It immediately broke when I upgraded to the AMD 7840U mainboard. I’ve been tearing my hair out for months trying to figure out why, with no luck. I think it’s related to the embedded controller, but if you have any advice on how to get it working on the 7840U series, I’d be really appreciative.

The embedded controller driver in the kernel does not yet support the AMD Framework Laptop.

A patch has been accepted which adds support for it: [v3,0/4] platform/chrome: cros_ec_lpc: add support for AMD Framework Laptops - Patchwork

It should be in the next mainline version update to the kernel (6.10, since 6.9 is in the release candidate stage.)

For an ubuntu-user, how would I implement that patch on my own system?
I’m nowhere near knowledgeable enough for arch, so if you could point me to a resource that could help, or even just break it down into crayons for me, I’d be super grateful.
