I have a question about controlling displays in a multi head system.
I have three monitors connected to my computer, and I want the
console to display on one of these and the other two to be unadorned.
I am running the current Debian distribution, which on boot displays
a desktop on all three screens.
Q: How can I prevent adornment appearing on the 2nd and 3rd monitors?
I am implementing a new version of a program I wrote perhaps ten
years ago, and ran it at that time under Mandrake Linux, which gave
me a cross hatch background on the secondary screens, allowing
my program to occupy the full screen real estate. My current
workaround is to use Fluxbox as a window manager, which has a
minimal presence on the monitor, but there must be a more direct
and complete solution to this problem. I've done my best looking
through the gui boot sequence, but I see nothing obvious there,
and a lot in those files is more then I'm up to.
I don't know if it's any help, but I've just inadvertently entered this
field. I wanted to hook my Aspire netbook (on Ubuntu NR) up to an
external monitor, so plugged one in, and it stayed black. I tried
'xrandr' (no arguments) from the command line, and besides listing the
displays, it caused the monitor to wake up and behave as you wish, with
no bars visible. Windows could be dragged from the netbook screen to the
monitor. When I booted with the monitor plugged in, it was as you
describe, the monitor showed the same display as the netbook.
So I'd suggest investigating xrandr, which ought to be configurable to
do what you need.
