I want to completely disable the output of any messages on the screen when the system boots. nomodeset, quiet - don't work properly for me. Error messages still appear. Ideally, I want to see a message on the monitor - "no signal".

The best I've been able to achieve is setting console=ttyS0, but I'm not going to use the serial port.

I tried to disable the framebuffer but that doesn't work either.

  • **console=none** causes the system to reboot. – descartes Jun 18 '23 at 15:48

loglevel=0 should disable everything except for kernel panics :-)

To switch off the monitor, add setterm to your initrd and run it on boot. This is distro dependent, and outside the scope of this question.

  • I want to achieve the behavior similar to the command: **setterm --blank force** – descartes Jun 18 '23 at 18:40

    This is a completely different question/issue. You seemingly want to power off the screen while booting, only I don't understand why. Add what I wrote to the boot arguments and then add `setterm` to your `initrd` and run it on boot. This is distro dependent, so I won't say how it can be done. – Artem S. Tashkinov Jun 18 '23 at 19:38
