How to make the boot screen display boot messages instead of the NVIDIA splash screen?

Greetings!

When setting up a system, I normally like to see the various boot messages that scroll by during boot rather than the splash-screen graphic as they can be incredibly useful.

In a “normal” Linux install, all I need to do is modify the boot parameter string to remove “quiet” from it.

Is there a reasonably easy way to do this on the Jetson Nano?  Or is this exclusively limited to the serial console?

P.S.
I found some data about modifying the boot-time arguments here:

But again, it sounds like I have to recompile a bunch of stuff in order to accomplish it.

Kernel cmdline is specified in /boot/extlinux/extlinux.conf.
You just do the same thing to remove quite from it as you would do on a normal x86 Linux PC.
No compilation stuff is required.

I tried that and, on booting the Nano, I still get nothing but splash screens until the desktop appears.

What do you see from this command?
cat /proc/cmdline

There is no update from you for a period, assuming this is not an issue any more.
Hence we are closing this topic. If need further support, please open a new one.
