I am attaching the Folder with all updated patches from rehabman , and EFI ssdt files from 51nb.com

It uses the latest applebacklightfix.kext, updated from applebacklightinjector.kext , to work these thing to do

  1. if you are using dsdt.aml remove PNLF patches from that
  2. download rehabman applebacklightfix repository (build one) https://bitbucket.org/RehabMan/applebacklightfixup/downloads/
  3. Download the lilu.kext from https://github.com/acidanthera/Lilu/releases
  4. copy ssdt_pnlf.aml to your refi/clover/ACPI/patched
  5. remove the blacklightfix from kernel to kext patches in config.plist(like using cloverconfigurator or any)
  6. now copy the rehabman backlightfixup kext and lilu release version kext to your /efi/clover/kext/other(or your Mac version)
7. or use my EFI attached folder, tested with both Highsierra 10.13.6 and Mojave 10.14

If back light setting are reset every boot, then simply remove emunvram efi file from drivers64 folder , x230 has nvram , no need for emulation on nvram

Thanks for your fixes and patches

I have doubts , what is major difference in apple backlight injector and fixup version
why applebacklightinjector was deprecated,
Is there any improvements in fixup version , like anti aliasing ?

AppleBacklightFixup.kext replaces AppleBacklightInjector.kext and the related KextsToPatch entry for AppleBacklight.
If you're curious, read the source code.

Anti-aliasing has nothing to do with backlight control.

Thanks @venkatnath3
The information and your EFI folder have been helpful. I've managed to solve the backlight control issue. Cheers.

Yeah... your ACPI configuration/CPU PM is really messed up (you should not be dropping the CPU related OEM SSDTs).
