Got nearly everything working cleanly on a Dell Insprion 5300 (~2019) except on boot the backlight takes a good 1-2 minutes to come on. In a brightly lit area I can barely see the ghost image of what is on the screen and can even log in and see desktop but the backlight takes some time to fire up.
I have the latest versions as of a week ago of relevant packages for Dells. I have not changed DVMT-prealloc since it is still Dell locked bios if that has anything to do with it. I think not since it is just a backlight issue. I want to make sure everything is spotless before I stop booting from USB opencore
