[SOLVED] TTY screen unreadable on Lenovo Laptop

Hello dear community,

I got myself a new laptop and wanted to install arch on it. But after booting into the liveISO the screen starts to be all jumbled up: It seems to spread the pixels of the tty output(all ttys are affected) across the entire screen (see attachment).
I hope someone can aid me in fixing this. I could potentially try to blindly set up an ssh server and do the installation process via an ssh session, but if this issue doesn't go away I fear using the laptop like it is now would be a bit bothersome - especially if I'm trying to fix things via the tty.
I'm using the latest arch iso (2019.10.01) and my Laptop is the Lenovo Legion Y540-15IRH.

Ah, an intel igp + nvidia discrete videocard system.

Which card is set as primary / boot first in firmware ?


Multi-init booting with apg Openrc and systemd coexisting
Automounting : not needed, i prefer pmount
Aur helpers : makepkg + my own local repo === rarely need them

@quellen: Thank you, appending nomodeset to the arg list solved the problem.

@Lone_Wolf: The BIOS setting was set to "Discrete Graphics". I'm not too familiar with video card settings in the BIOS. Should I change it to "Switchable Graphics"? I'm planning on only using the nvidia card.

Keep it on discrete if that's your plan. Once you have the prop drivers set up nomodeset shouldn't be needed any more (and you might want to rather replace it with nvidia-drm.modeset=1 )
