[SOLVED] Making the external monitor faster(?) on a laptop

This issue might sound silly but it's kind of irritating since it happens on every boot I do.
I'm currently running sddm + hyprland on a laptop with an external monitor. The laptop monitor is disabled 24/7 since I only want my external monitor to display but I'm using its keyboard so I can't just close the lid etc. Anyways, my booting is kernel (both monitors) then sddm (laptop monitor flickers with external disabled then changes to external main, laptop disabled) then hyprland (laptop monitor flickers again with external disabled again then changes to external main, laptop disabled).
My external monitor is slower than my laptop display so it takes some time to display video each time it gets disabled. Assuming I'm waiting for a picture each I want to login, it takes around 20s total to boot in, whereas the single laptop display would do it in less than 10s
So is there a way to prevent this back and forth between booting, sddm and hyprland? I think KMS might do what I want but I can't find further info concerning my same setup

Why are you running SDDM itfp?
You could just autologin into a (locked?) Hyprland session?

You can tell the kernel what outputs to enable and which not: https://www.kernel.org/doc/Documentation/fb/modedb.rst
If you leave the Hyprland monitor config alone, this should allow you a direct boot on the external monitor (when kms kicks in and after the bootloader) - also see https://wiki.archlinux.org/title/Kernel … _KMS_start

It's leftovers from using KDE. I disabled xorg settings for setting up the screen in sddm and added kms to the hooks (i forgot to add it back during some driver issues in the past), it seems to have sped up the monitor time by a lot so it's solved I guess. Ty for the tip for hyprlock though
