connected the vga card

baseboard.
Which one? Does the baseboard also have a keyboard,
mouse input?
I have connected a monitor to the vga card.
When i boot linux from minicom, i could see all the
kernel log messages
on both the minicom and vga card monitor.
You will be passing something like "video=" option to
the kernel command line.
But on the
vga monitor, i
could not see any messages after asking for login as
below:
Usually, the hardware is designed such that the
keyboard/mouse on the baseboard functions with the
on-board VGA. Not sure which one you are using or
which Linux kernel you are using.
Though i am entering my login and passwd at the
minicom, nothing comes
on to the vga monitor.
Because input/output goes to the serial port _and_ is
not redirected to the VGA.
But i am able to write to vga
monitor using the
following commands from minicom:
# echo "Hello" > /dev/tty1
Sure, hardware is visible to all.
My requirement is to get on the vga monitor whatever
i am typing on the
minicom after logging into the linux like .
My question is "Why?".
The baseboard is supposed to be converted to an
end-product. Serial port is only for developers. An
end-user will use the on-board VGA, keyboard, mouse to
use the system, rather than the serial port. But, if
you want to do it, you also need to redirect the
serial buffer data to the framebuffer driver.
