[Guide] Laptop backlight control using AppleBacklightFixup.kext

Can't see how the two are related, but that's okay. I will figure it out myself.

Your ioreg clearly shows AppleBacklightInjector.kext not present/not loaded.
My suggestions:
Read post #1.
Install kexts as recommended.

Hey,

I did try to install the kext in /S/L/E but with the same result. :(
I then booted in safe mode and, while graphics acceleration didn't work, your extension was loaded. This makes me believe that there is an issue with the way that I have enabled graphics acceleration (dsdt patch, clover kext patch and patched framebuffer) and the injector kext.
Not sure if the attached files from safe mode help...

Either way, I will see what I can find.

Thanks.

You cannot expect it to work in safe mode.
Boot normally and attach 'problem reporting files'.

No "Problem Reporting" files attached.
Read FAQ, "Problem Reporting" again. Carefully. Attach all requested files/output.
https://www.tonymacx86.com/threads/faq-read-first-laptop-frequent-questions.164990/
Use the tool mentioned in the FAQ, that way it is less likely you'll omit something.

The FAQ has very specific instructions for the case you cannot boot.

No "Problem Reporting" files attached.

Also, full "problem reporting" files without the kext installed may also be useful in determining your mistake.

Hey,

I have attached two zip files. "ThinkPadX201_verbose.zip" contains the reporting files when I boot the system with the kext and in verbose mode. Picture "Verbose_1" was taken just before the system reseted and picture "Verbose_2" shows the last screen that I can see before the system restarts.
The second zip file ("ThinkPadX201_no_kext.zip") contains all the files without the AppleBacklightInjector.kext installed.

Let me know what else you may need.

Thanks.
