Cannot change RGB light on my ACER Nitro AN515-55

[GamerMine]

Hello, After installing the module, I try to use one of the templates and it does not work. It's not changing anything on my keyboard. I use Ubuntu 21.04. The linux header is installed. I hope I can use this module =)

Hi Did you disable secure boot in bios? As reported by https://github.com/JafarAkhondali/acer-predator-turbo-and-rgb-keyboard-linux-module/issues/7, it should work for your laptop.

Thank you for your response =) Yes the Secure Boot is disabled in bios =) Maybe I did something wrong, here is the steps I followed :

• I cloned the repo
• The Secure Boot was already disabled so I skipped this step
• I verified that I had the linux-header installed
• In a terminal I executed this : sudo ./install.sh
• Then I tried to run : python3 facer_rgb.py -m 1 -s 4 -b 100 -cR 255 -cG 0 -cB 255 but it didn't work

Can you try these steps as well?

sudo ./uninstall.sh sudo apt update && sudo apt install linux-headers-generic linux-headers-$(uname -r)

add #include <linux/uaccess.h> and #include <asm/uaccess.h> after line 32 of src/facer.c ( first try to add them separately, if none worked, try to add them both)

sudo rm /dev/acer-gkbbl-0
sudo ./install.sh

and try running python script with sudo. It should work then. If not, check the output of ./install.sh command and dmesg

[GamerMine]

So I tried everything but it is still nor working. Here is the output of sudo ./install.sh :

And there is the last few lines of the output of dmesg :

Oh, and when I try to delete /dev/acer-gkbbl-0, it says that the file does not exist

I think this has something to do with vmlinux.

try these

echo "deb http://ddebs.ubuntu.com $(lsb_release -cs) main restricted universe multiverse" | sudo tee -a /etc/apt/sources.list.d/ddebs.list
echo "deb http://ddebs.ubuntu.com $(lsb_release -cs)-updates main restricted universe multiverse"  | sudo tee -a /etc/apt/sources.list.d/ddebs.list
apt-get update
sudo apt-get install linux-image-$(uname -r)-dbgsym

Okay so I have installed the vmlinux thing and it is not complaining about it anymore. But it is still not working =) The sudo ./install.sh output as slightly changed so here is it :

EDIT : I rebooted my laptop and it is now complaining about vmlinux again =( I have verified that vmlinux is installed and it is. I think it is just nof finding it

[JafarAkhondali]

hmm, try installing other kernels for your distro. I am pretty sure that this should work with your laptop, it's just a software problem

[GamerMine]

I updated the kernel of my laptop and it is still not working. My previous kernel was 5.11.0-18 and now it is 5.11.0-34. When recompiling (when I add or remove the two includes) it always complain about vmlinux. Is it normal that in dmseg it says : acer_wmi: Acer Laptop WMI Extras unloaded ?

[JafarAkhondali]

Then give Ubuntu live a try. Unloading acer-wmi is normal, cause my repo is the extended version of acer-wmi

[GamerMine]

Okay, so I tried in an Ubuntu live and it doesn't work either. I start thinking that my computer is not compatible =( Maybe I have a slightly different revision of the Nitro AN515-55 ? I really don't know

[JafarAkhondali]

If you have a 4-zone RGB keyboard, then this should work for you

[GamerMine]

Okay after a lot a search I found that the AN515-55 model has a lot of different revision and I figured out that if the keyboard has a red painting when it is off, then the keyboard is not RGB and unfortunately my keyboard have that paint. I'm sorry for all of this =)
