I'm trying to install arch for the first time and I'm using an old laptop i had lying around.
I've come to the conclusion that this laptop's dgpu is dead as i get video output up until the OS initializes. (With arch I can't get past choosing the installation medium, with windows I don't get any output when the os should start loading the login screen) The screen goes black but doesn't turn off and in windows the keyboard's rgb lights respond to fn presses (though this doesn't happen in arch)
I've been searching for a way to prioritize the igpu as a way to circumvent the hardware failure, though I'm starting to think this may not be possible in the kernel parameters.
Edit: managed to get through posting windows by turning off turbo boost. gonna try and disable the dgpu once i get arch set up as i think it's a power issue
If software methods won't help, you can google smth along the lines of "$laptop_model uma"; usually disabling dgpu in hardware is quite simple, like lifting one coil
