[SOLVED] FW 16 Keyboard backlight

That’s neat.

But also still Chromium. It’s not purely about Google, it’s also about a separate browser rendering engine. Although for just using it for this, perhaps it’s OK.

I also have it just in case a page doesn’t work with my other, firefox-based browsers, due to being too chromium-optimized. And if you use the portable version like me, you don’t have to install it at all.

I dislike AppImage in general, but I suppose I can hold my nose and use it, if I must, for the occasional one-off usage.

Why use the AppImage, if you can use the " Portable Linux 64-bit" release instead?

When I choose “Authorize device +”, I get this message:

I am using a Framework 16 with Fedora, and I tried both Brave Browser and Chromium. Same results.

What version of Fedora?

This link reports that WebHID is available, correct? webapicheck.com/apis/webhid-api

You may need to add udev rules.

Click to show instructions

docs.qmk.fm/#/faq_build?id=linux-udev-rules

place this file into /etc/udev/rules.d/.

Once added, run the following:

sudo udevadm control --reload-rules
sudo udevadm trigger

This has been needed on Fedora 39 KDE and Silverblue.

If anyone needs to do this on a different distro please post your distro.

Bingo! Now it works on keyboard.frame.work and with the standalone app.

I get these same errors, I have installed the udev rules, webhid is available, I am using Ubuntu 24.04, both Chromium and Chrome do the same thing.

EDIT: Also none of the hotkeys listed for controlling the lighting do anything except Fn + Space which cycles through effects

Are they snap packages?
Ubuntu will install snap instead of normal .deb packages. But snaps can have permission issues. Ubuntu also has the nasty habit of hijacking some apt installs and just redirecting them to snap.

Is Fn + Space just cycling through brightness levels? If you don’t have an RGB keyboard then I don’t think any other effect keys apply to your keyboard.

No mention of OS. As procedure fails inder Fedora 40, I’m assuming windows.

It works under Linux as well.

Thanks. Please post the udev rule(s)

The instructions are in a collapsed section, which you can click to show. Sorry, that wasn’t clear. I edited it.

No, initially it was snaps, but I changed to regular deb packages for this

Not brightness, cycles through different breathing speeds. All I want is for the backlight to actually stay on, but so far nothing allows that to happen.

This is really some odd behavior. I activated that breathing by accident just today. There was certainly no VIA app involved. I think I was trying to hit something like pos1 or something when whatever I hit triggered the breathing. Using the VIA website with the udev rules did fix it for me. The question is, what key combination activates that mode in the first place?

That’s odd. Even when I somehow activated it by accident today, Fn + Space was still changing brightness. Maybe @Matt_Hartley or someone else at Framework would be so kind and shed some light on this situation.

Try Fn + C.

I don’t see it listed on the FWL16 hotkey page, but Toggle backlight breathing, BL_BRTG, is on the default keymap under Fn + C. I’m guessing it’s an oversight that it wasn’t listed on the hotkey page.

Thanks, Fn+C did stop the breathing and now with that stopped Fn+Space does adjust brightness.

Looks like I am late to the party, looks like it is resolved now. Glad to hear you have it sorted.

Just stumbled upon this too when my non-RGB keyboard switched to breathing instead of static backlight. The FN + C key combo should really be listed on this page
