Hey there. I have a Lenovo Legion 5 (not Pro) and I've tried running the executable and get this error:

thread 'main' panicked at 'Error: Couldn't find device', src/main.rs:8:21 note: run withRUST_BACKTRACE=1environment variable to display a backtrace

When doing cargo build it complains about

"error: failed to run custom build command for `scrap v0.5.0"

Here is the full log

Hello

Legion 5 Pro: 16ACH6H 4 zone RGB keyboard Windows 11.

I wanted to open the program but literally nothing happens. (even in compability mode) Trying to open the latest version and 0.7.0 do the same thing.

I try to open it and maybe it instantly crashes but I see that nothing is happening. It doesn't give any errors, just completely nothing.

Also installed Rust but it didn't help.

When I open the app is says, "A valid keyboard model was not found. It may be due to a hardware error."

Lenovo Legion 5 Pro Gen 7 AMD Model: 16ARH7H Type Model: 82RG001MUS Win 11

As shown in the title, a toggle which can start the application but by putting it on the system tray so it can be opened from there, ideal for startup when booting up the machine just not to make the setting console to stay there unless i click the red X or by minimizing it, it can make things cleaner

Using Kubuntu with Kernel 5.13.0-25-generic and Plasma version 5.23.5, when using these two modes nothing happens. Kindly look into this issue.

By the way, awesome app my dude

I just want to leave a experience with the app, maybe is just my fault, i wanted the app to run exactly at the time the machine turn on so i dont have to manually open it everytime i log in, so i created a task in task scheduler to open the app as soon as the machine boots up, before i log in (so i had to type administrator password to create the task).

Next time my machine booted up, apparently the function keys like brightness control, airplane mode, microphone, touchpad toggle and lenovo special key stopped working, also the status LED for the num lock key got stuck and it couldnt turn it off even if the num pad wasnt active, same goes for the caps lock, which was the opposite, it couldnt turn on even if the caps lock was active.

Volume keys, num lock, caps lock worked fine, and the Fn Lock in Esc key worked only if i turn it on through software, and i can even control the normal rgb as usual through the app and lenovo vantage software, the only thing broken was the rest of the Fn Keys and the Status LED on some.

Maybe it was just my bad but the only way to solve this problem, i had to do a factory reset, contacted lenovo support and they brought me a tool to reinstall windows from scratch, so the problem was solved there, a little advice to someone who could do the same, and this thing happened, so if anyone with their 5 pro could try this (if the issue exists you may have to factory reset the laptop using the lenovo recovery key to fix it) and confirm this issue since i dont want to factory reset my 5 pro again, so the dev can make a failsafe in this regard if that was the case or not because im dumb enough to do that kind of stuff

Problem Every time I try to run this as a non-root userI get the following error:

floating point exception (core dumped)

I have added the needed udev rule and reloaded the rules, so I'm not sure why it won't launch. However, it does work when I run it as root. Although that gives me this error:

pango_font_description_set_absolute_size: assertion 'desc != NULL' failed

Notes I checked to see if pango was installed, and version 1.50.7.1 is present

I didn't build from source, instead I used the zip archive

I'm not sure what to do at this point besides trying to build from source and seeing if that works. Any other suggestions?

Question?

The application is compiled and it's a success.. The main Question is how to run the application for the first time.?

System Info:

My current device is Lenovo Legion 7 Slim. Specification are:

• 16GB Ram
• 512 SSD
• Pure Arch Linux
• AMD Ryzen 7 5800H
• Nvidia RTX 3060

Im just seing that the program closes itself after one or two suspend action of windows, dont know what is happening but everytime i wake up my laptop from sleep, the program quits itself and stop running, having to open it again to summon the custom lightning

Hi. Props to you for putting this program together, it works fine on my Legion 5 (15ARH05H).

It's working fine overall but, at times the program is reportedly using 8%+ CPU including while not much/anything is going on the screen.

So, to minimize the load on the CPU I think it's be nice to have a parameter to set the rate of the screen reading so that we can have it respond quick enough to our preferences while also saving some system resources. I know, these are beasty machines and all but for one I'd be fine with even half the detection rate/reaction time knowing that the program isn't doing that at times 8%+ processing anymore. :D

Hi again and thanks for implementing an user-adjustable FPS limit for the AmbientLight effect. With that provided I managed to make an altered version of it that matches my preferences more closely.

Do you accept pull requests for new effect profiles here? And if so how should be the code of the new effects formatted?

Since last version v18 everytime the pc boots up and opens the RGB app, now there is a console window that also opens with it, i dont know if was the updated code of the app that causes this, but in the console window i cant type anything, is just a giant black box that doesnt do anything and i can close it perfectly, tried finding solutions from my end if it was something that windows updated and being the reason why the console window is appearing, but nothing so i decided to post this "issue" here.

When running linux and using this tool, I can only modify one preset, the other 3 remain as default: pulse, wave and fade. On windows, upon setting it with the proprietary Lenovo software, it loads them up upon booting.

Is this limitation caused by proprietary firmware level stuff, reverse engineering difficulties, or what? Would definitely like to help on this matter as it is kinda annoying having some RGB on your face while I switch to my preset at 3 in the morning.

When inputting numbers into the boxes, this application often crashes in GUI mode. These boxes can also be resized left or right, which is definitely not supposed to happen. Here is the crash log.

No subcommands found, starting in GUI mode. To view the possible subcommands type "legion-kb-rgb --help".
The application panicked (crashed).
