Hello everybody, EDIT: Of course shortly after posting this I decided to reboot, and I’m unable to recreate the below issue. I have a sneaking suspicion it will return though (reboot to resolve is no good resolution). So any wayward troubleshooting soul that wants to help me recreate/resolve the issue, feel free to reply! I am running Debian 12 on my new Framework 16, the AMD Ryzen 7 7840HS model w/out the additional GPU. The keyboard backlight is acting odd. It continues to fade in and fade out, and it doesn’t consistently respond when I press Fn+Space to control it. I also have the number pad installed, and Fn+NumEnter doesn’t appear to be controlling that backlight either. I’ve alternated the Fn lock to see if this was a dumb user error, but it still isn’t working. (Sidenote: some sort of indicator light to show if Fn lock is enabled would be really helpful.) I’m combing my system logs to see if I can find an error of some sort, but I don’t know where to look really. Any help would be appreciated, thanks! ---

Which keyboard do you have? Can you check what it’s set to in the lighting tab in Via ([keyboard.frame.work](https://keyboard.frame.work/))? ![Screenshot from 2024-03-31 fwl16 lighting 2](https://us1.discourse-cdn.com/flex001/uploads/framework3/original/3X/4/4/44fb7515ab1721179abe72e43db416b1214473e1.jpeg) ---

So I just opened that link in Google Chrome and it’s throwing a bunch of errors, see here: ```auto timestamp, productName, vendorId, productId, message 00:42:15.010, Framework Laptop 16 Keyboard Module - ANSI, 0x32AC, 0x0012, "Failed to open the device." 00:42:15.041, Framework Laptop 16 Keyboard Module - ANSI, 0x32AC, 0x0012, "Received invalid protocol version from device" 00:42:19.242, Framework Laptop 16 Keyboard Module - ANSI, 0x32AC, 0x0012, "Failed to open the device." 00:42:19.247, Framework Laptop 16 Numpad Module, 0x32AC, 0x0014, "Failed to open the device." 00:42:19.248, Framework Laptop 16 Keyboard Module - ANSI, 0x32AC, 0x0012, "Received invalid protocol version from device" 00:42:19.253, Framework Laptop 16 Numpad Module, 0x32AC, 0x0014, "Received invalid protocol version from device" 00:42:38.774, Framework Laptop 16 Keyboard Module - ANSI, 0x32AC, 0x0012, "Failed to open the device." 00:42:38.779, Framework Laptop 16 Numpad Module, 0x32AC, 0x0014, "Failed to open the device." 00:42:38.780, Framework Laptop 16 Keyboard Module - ANSI, 0x32AC, 0x0012, "Received invalid protocol version from device" 00:42:38.785, Framework Laptop 16 Numpad Module, 0x32AC, 0x0014, "Received invalid protocol version from device" ``` I authorized Google Chrome to access my HID devices like it asked. Unsure what’s going on there. ---

Chrome is installed as a normal system package, right? Not snap, flatpak, or AppImage. ---

I downloaded the .deb from [chrome.google.com](http://chrome.google.com) and installed it via: ```auto sudo apt install ~/Downloads/google-chrome-stable_current_amd64.deb ``` ---

You may need to add udev rules. Place [this file](https://github.com/qmk/qmk_firmware/tree/master/util/udev/50-qmk.rules) into `/etc/udev/rules.d/`. Once added, run the following: ```sh sudo udevadm control --reload-rules sudo udevadm trigger ``` Then reopen your browser. If still not working, check that /dev/hidraw\* belongs to the plugdev group. `ll /dev/hidraw*` example output `crw-rw-rw-+ 1 root plugdev 240, 3 Mar 22 17:28 /dev/hidraw3` ---

Thanks MJ1, your first suggestion re: udev worked. I just accessed that website and the effect was set to “spiral” something. I’ve turned effects off, which I imagine will fix this issue. Is that your assessment as well? P.S. IMO a webapp to pass HID devices to configure stuff like a keyboard is silly. Why can’t that be controlled locally on my PC? _sigh_ ---

> [@Mark-D](#): > > P.S. IMO a webapp to pass HID devices to configure stuff like a keyboard is silly. Why can’t that be controlled locally on my PC? _sigh_ Totally agree. Someone said they are working on a Vial port. Vial offers desktop apps for Windows, Linux, Mac. And still offers a website GUI for those that so desire. > [@Mark-D](#): > > I just accessed that website and the effect was set to “spiral” something.

I’m unsure which keyboard I have any further than it’s a backlit US/English keyboard. I just checked lspci and it’s details aren’t listed. The backlight does appear to be working now!! Thanks, again. Can I just edit the title like I see in other posts to say [Resolved] to mark this resolved? ---

If you have the option then a pencil icon shows next to the title which you can click. ![fw edit thread title 2023-09-22](https://us1.discourse-cdn.com/flex001/uploads/framework3/original/3X/f/e/feebc5c056fa1c068dbf3c19f56a54f9bd4f27fd.png) Clicking the pencil will bring up edit options. ![fw edit thread title b 2023-09-22](https://us1.discourse-cdn.com/flex001/uploads/framework3/original/3X/6/0/60b63b10f0842ffce8942b1f48ee533f4d8dd782.png) ---

My keyboard was set to “breathing”. No idea why… ![image](https://us1.discourse-cdn.com/flex001/uploads/framework3/original/3X/d/3/d305be7981dab73d8ca35a7cb05f04da14682043.jpeg) ---

For the keyboards, Fn+C toggles Backlight Breathing on/off. For the numpad, Numlock off + + (the plus symbol) toggles Backlight Breathing on/off. It’s missing from Framework’s hotkey list, but it’s present in the current firmware’s keymap. > [@List of default keyboard mappings](https://community.frame.work/t/list-of-default-keyboard-mappings/55414/3): > > You can find links to the hotkeys & a lot of other FWL16 info on this page [frame.work/laptop-16-support](https://frame.work/laptop-16-support) Hotkeys on the Framework Laptop 16 Keyboard [Learn more](https://knowledgebase.frame.work/hotkeys-on-the-framework-laptop-16-keyboard-rkYIwFQPp) Default Keymap for the RGB Macropad [Learn more](https://knowledgebase.frame.work/default-keymap-for-the-rgb-macropad-rkBIgqmva) Default Keymap for the Numpad [Learn more](https://knowledgebase.frame.work/en_us/default-keymap-for-the-numpad-rJZv44owa) Customize key map and RGB lighting [Customize](https://keyboard.frame.work) Note that there is an error / missing hotkey on those lists, at least for the currently shipping firmware on the keyboards.
