Added a poor mans version of DKMS

I've made it create a script for the service. It stores the kernel version the module was compiled for in this script, on boot if they don't match it will recompile the module, and update the kernel version stored in the script.

I forgot to mention I'm pretty sure this covers #113 and #137

I don't have a "/home/o0xwolf/.config/bspwm/bin/facer_rgb.py" file. The only files affected by this that should be in /opt/turbofan. Can you tell me more about where you got this error from, and what you did to get it?

[mmsaeed509]

/home/o0xwolf/.config/bspwm/bin/facer_rgb.py is the same script /opt/turbo-fan/facer_rgb.py

/opt/turbo-fan/facer_rgb.py gives the same error

/opt/turbo-fan/facer_rgb.py

I believe this is a problem in upstream, I installed the base version, restarted my computer, and then ran install_service.sh again after restarting my computer, and got the same problem. I will attempt to fix my branch so that it can be installed repeatedly without restarting, but as far as I can tell this problem exists independent of the changes that I have made.

[LarryTheMagicDragon]

I believe I have fixed the issue. As far as I can tell it is caused by calling insmod on the facer module while having a version of the facer module loaded. the install script, and service script remove /dev/acer-gkbbl-0 and /dev/acer-gkbbl-static-0, if the module cannot be reloaded it will fail to recreate them. on my system the problem seems to be fixed, I am now waiting for feedback from others

On PH315-54; kernel version 6.12.1-arch1-1 (64-bit), both install.sh and install_service.sh runs but not works (the turbo mode is not on when the turbo button pressed). Here's the log of install.sh:

@Ki-wimon Does the RGB still work? does "lsmod | grep facer" show any output?

[Ki-wimon]

I'm sorry that I downgrade my linux kernel to 6.11.9 in the end. I didn't test that.

[LarryTheMagicDragon]

@Ki-wimon Thank you for your input. I'll see what I can do to resolve the issue

[LarryTheMagicDragon]

@Ki-wimon I have made some modifications and I'd like to know if this fixes turbo for you. If you run 'journalctl -f | grep facer' in a separate terminal and then install it, it will give a much clearer view of what is happening on your system.

I know I wasn't asked this but I'm having issues as well so hopefully this will help.

Using "lsmod | grep facer" returns nothing for me.. Hope this helps!

@OVA-Charmao I've looked at your log message and it looks like you're trying to install the base version. I tried both my pr, and the base version as a sanity check, and I only have those errors on the base version. You should try this branch by running 'git clone https://github.com/LarryTheMagicDragon/acer-predator-turbo-and-rgb-keyboard-linux-module.git' and the attempting to install as you normally would

[OVA-json]

I managed to get it to actually work. I thought I was doing the proper git on your fork of the main branch but the README.md file on that git doesn't show the LarryTheMagicDragon git. It still showed the JafarAkhondali one. That was my fault as I wasn't paying attention. Thank you!

[LarryTheMagicDragon]

@OVA-Charmao Thanks for letting me know, it really helps!
