How to mute kernel messages at startup in Arch Linux?

Question

I am playing around with a custom Plymouth bootsplash in my Arch laptop. I have followed this tutorial and everything went OK.

My problem is that, after selecting Arch on Grub (even when I only have Arch installed), a blinking cursor appears on the top left corner of my screen, makes my whole bootsplash blink and floods the screen with messages.

Is there a way to deal with it? Following this answer didn't work for me, as I /etc/sysctl.conf does not exist in my system.

Solution

Add vt.global_cursor_default=0 (as a parameter) to the end of the GRUB kernel boot line for your Linux OS (the line that starts with linux).

That will hide the blinking cursor during boot time.

You can edit a grub boot line at startup too; might be worth trying this first before modifying grub config (don't forget to sudo update-grub to make changes active).
