Fix black screen issue on boot #42

Closed vinhtq115 closed 3 years ago

vinhtq115 commented 3 years ago

Added enable-backlight-registers-fix to fix black screen for 2-4 minutes after booting, which happens quite randomly.

From WhateverGreen's boot arguments:

-igfxblr boot argument (and enable-backlight-registers-fix property) to fix backlight registers on KBL, CFL and ICL platforms.

what does the black screen look like? is it "dark" and cant increase brightness even the brightness level is maximum?

It boots to a black screen randomly (even at full brightness), it is not common but happened. The solutions were restart or let it sleep and wake it

Mostly happened to me when i was on windows and immediately restarted to boot macOS

13thdemarch commented 3 years ago

oh... so it is i always restart if i met it. btw when back from WIndows, the recommendation is shut down then power back. If restart, some drivers on Windows will affect to macOS

Juan-VC-gh commented 3 years ago

That could be what was causing the issue. Will shutdown then, thanks for the tip!
