π drm_helper_move_panel_connectors_to_head(9)
okay so this one's a keeper from the Kernel API Manual β literally the glow-up your connector list didn't know it needed β¨
πΈ NAME πΈ
drm_helper_move_panel_connectors_to_head β bestie, this is the function that moves your panels to the front of the connector list. slay.
π SYNOPSIS π
void drm_helper_move_panel_connectors_to_head (struct drm_device *dev );
π¦ ARGUMENTS π¦
devβ the drm device you're operating on. that's the one, that's the main character π«Ά
β¨ DESCRIPTION β¨
okay so here's the tea π΅ β some userspace code out there presumes that the first connected connector is the main display. like, it just assumes. and that's where it's supposed to display stuff like, idk, your login screen?? so for laptops, that connector lowkey has to be the main panel. no pressure or anything π
so use this function to sort all your panels β and by "all your panels" I mean the (eDP/LVDS/DSI) ones β to the front of the connector list. π―
instead of, and I cannot stress this enough, painstakingly trying to initialize them in the right order π like bestie please just call the function, you do not need to suffer.
the way this saves you from manually ordering everythingβ¦ iconic. periodt. π
