In Topic: Cannot Get Brightness to Work with AppleBacklightInjector

17 October 2017 - 10:32 PM

I have been posting about my ongoing problems getting brightness to work in High Sierra using AppleBacklightInjector.kext.  I can get the slider bar to show in SysPrefs/Display and it also works using my brightness keys.  However, the slider doesn't do anything - there is no change in screen brightness.  This is not effected by sleep/wake.


Your laptop probably doesn't use the IGPU PWM for backlight control, therefore it is not compatible with AppleBacklight.kext (would not be compatible with IntelBacklight.kext either).
Your only choice is ACPIBacklight.kext + Brightness by bergdesign (for controls on the menu bar, since native controls won't work).

Rev 4250
XCPM patch will no more be unconditional.

		<key>KernelXCPM</key>
		<true/>

Default value is <false/>. 
It can arise some problems because old revision has default to true.
But many users can't boot at all because of this. Let it be conditional setting from config or from Clover GUI.


Why add "BOOLEAN KernelXCPMAllowed;" to Platform.h when it is not accessed anywhere?
And KernelXCPM is just a synonym for KernelIvyXCPM?

Use this one for Alps touchpad


That one is closed-source, violating the APSL.

There is also some ALPS versions of my version of VoodooPS2Controller.kext floating around (I don't track it, no ALPS hardware here).
Assuming one prefers open source, that is...

I have no good Trackpad driver. Only VoodooPS2Mouse or VoodooPS2Trackpad by rehabman which works exactly the same. They have no scroll function.


Two finger scrolling (and other features) are available with compatible Synaptics hardware.
You probably don't have Synaptics.
Search for PS2 kexts appropriate for your trackpad hardware.

Yes this is an issue that has been bugging many people since HS developer beta 6 or so.

It seems to affect only people with dual Nvidia cards (I have 2 GTX1080s) and I am stuck too.

 

As explained by Rehabman over at the forum that shall not be named, IONDRVSupport.kext fails to load and then the WindowServer process ends up failing to load, and launchd gets stuck trying to respawn it forever.

 

This is the VESA mode driver for nvidia cards that don't work out of the box (maxwell and pascal basically).

 

I have built a live USB installer using the "restore directly from BaseSystem.dmg" technique, and I have copied nvidia webdrivers over and rebuilt kernelcaches etc. When I boot I can watch them load and get registered (once for each card), and then the screen tries to change graphics mode and screen goes blank but stays powered on forever - so this is not the usual AGDP/MacPro6,1 issue (have taken care of it using existing well-known solutions) but a new issue as has been described multiple times already in this forum e.g. by fabiosun. I don't get a moving mouse pointer though, have never seen that. To sum up even trying to install with nvidia webdrivers loaded fails. I even used Rehabman's tricks to only load the webdrivers for one card, still failed with same blank screen. Obviously deleting IONVDRVSupport.kext altogether is not a solution either as it seems to be necessary to load the webdrivers and without it the boot process gets stuck in console mode.

 

In short even with nvidia drivers baked in there is no way I can see to make the installer work. Only solution at this stage seems to be to remove one card from the motherboard ... 

 

In order to use the IONDRVSupport.kext disable method (either by removing the kext or disabling it by injecting bogus name/IOName/class-code), you must then have another graphics device you can use for the install.  If you have a onboard Intel IGPU, use that, otherwise use another compatible graphics card that works without this issue.
