    Hey guys,my notebook model is dell precision 7510 with radeon w5170m graphic card,this card is like r9 m370x,cpu is 6820hq,I had disabled the switchable graphic card option in bios.Now I had completed mojave installation,but when boot into macos I got a yellow screen and moveable mouse point,I didn't see the start screen of macos,what the hell  is this?

And I can boot into recovery mode ,I can see anything that recovery mode shoud have.

I installed whatevergreen ,In the clover config.plist ,I didn't set anything in graphic ,I didn't set fakeid,I didn't set special boot flag.

And next ,i would check the device ID of the graphics card.

  

 You should be able to boot in safe mode ( -x ) ?

I seted smbios as MacBookPro13,3,and the device ID belong to this graphic card w5170m is 68201002.

If I set -x boot flag ,I get black screen without mouse point after boot.

And I had try set radeon deinit in clover configurator,but I got yellow screen with mouse point  after boot.

fixed this problem,see https://osxlatitude.com/forums/topic/11048-amd-radeon-hd-7750-supported-by-mac-os-mojave-catalina/.

I have added radpg=15 to boot flag.

But I get a now problem,no backlight control support,I didn't find helpful info about backlight control from https://github.com/acidanthera/WhateverGreen/blob/master/Manual/FAQ.Radeon.en.md .

And the whole boot took 2 minutes ,too long .
