Turn off quiet boot?

[Ron Hunter-Duvar]

Does anyone know how to turn off QubesOs' quiet boot (splash screen
instead of kernel messages)?

I like to see the messages during boot (and shutdown). More than once
I've caught a lurking problem (although it scrolls by fast, those red "[
FAILED ]" messages really stand out).

I've removed the "quiet" keyword from the "kernel=" lines in
/boot/efi/EFI/qubes/xen.cfg, but that only gives me the first page or
so, and still brings up the splash screen. Pressing Esc gets me back to
the messages, but I'd like to have it stay there.

This is with EFI booting. No grub (don't even have a grub.cfg file in
/boot).

Thanks,

Ron

I'm not sure how to turn it off, but you can toggle it on demand by
pressing F2.

Removing the "rhgb" (historically "Red Hat Graphical Boot") parameter
will result in defaulting to text boot instead of plymouth splash
screen. You can still switch back and forth by pressing Esc.

The "quiet" parameter, as you found out, only affects early kernel
boot messages (before initramfs is mounted and plymouth can be started
started).

With grub you can also disable plymouth entirely by using
plymouth.enable=0 in /etc/default/grub.

Maybe that also works with EFI.

Thanks, Patrik, that did the trick. Never thought to question what the
"rhgb" was for.
