复制代码 Brightness fix (Haswell/Broadwell)的是:- #Maintained by: RehabMan for: Laptop Patches
- #graphics_PNLF_haswell.txt
- # This patch enables the brightness slider in SysPrefs->Displays
- # and will also enable activation of sleep mode by closing
- # the laptop lid.
- #
- # This particular version is intended to be used with ACPIBacklight.kext
- # although it can also be used with AppleBacklight.kext,
- # provided AppleBacklight.kext is patched to recognize your
- # display or an injector is used to set brightness levels.
- #
- # See this thread for more information:

- # (also read any linked threads)
- #
- # Note: This patch should be applied to the DSDT or SSDT that defines
- # your integrated graphics device (always at _ADR 0x00020000)
- #
- # This patch works for both Haswell and Broadwell graphics
