[Solved] Black screen after wake/intel hd 520 / mojave

Recommended Posts

Currently I have a Dell inspiron 7359 running Mojave. Everything is working after some patches and kexts:
Audio
Wifi (Dw1560)
Continuity
Sleep
Backlight
Battery status


However, when system wake after sleep, internal monitor is black. Could simenody point me what to do to fix this?

 

Things that I tried to fix this:

1. Change ig-platform

2. Change edid

3. Patching backligth


Thanks.

Disable "Boot graphics glitch", not needed with Whatevergreen.kext, besides it's for 10.10.x->10.11.x

Disable OSID to XSID  and _OSI to XOSI renaming and remove SSDT-XOSI.aml-> is set to Windows2012.

I2C touchpad was recommended to use Windows 2015 which is what you have patched in your DSDT.

 

Not sure why you have patched or modified AppleHDA.kext in /S/L/E, you're using AppleALC.kext for audio. Should restore a vanilla version of AppleHDA.kext to /S/L/E

Repair permissions and rebuild cache

Reboot

Test sleep/Wake

If you shine a flashlight to the screen do you see anything?

Can you switch the brightness slider up?

Did the system with black screen or it didn't wake at all?

Does power light blink when it's asleep?

Does external monitor work on wake?

 

Have you tried disabling hibernation?

sudo pmset hibernatemode 0

sudo rm -f /var/vm/sleepimage

sudo pmset hibernatefile /dev/null
