Serial and graphical console at the same time

[Christian Auby]

How would I go about setting up grub2 with both serial console and
graphical console?

There are three related settings in /etc/default/grub:

GRUB_CMDLINE_LINUX
GRUB_TERMINAL
GRUB_SERIAL_COMMAND

I don't any have problem getting the serial to work alone, but I can't
find any mention of using both in the manual.

The values I'm currently using (that only gives me serial):
GRUB_CMDLINE_LINUX="console=tty0 console=ttyS1,115200n8"
GRUB_TERMINAL=serial
GRUB_SERIAL_COMMAND="serial --speed=115200 --unit=1 --word=8 --parity=no
--stop=1"

OS is Debian testing, kernel 2.6.32-trunk 64bit in case this is relevant.

thanks,

Christian
