Hello,

I have a netboot with a screen on the VGA output.
I start my computer on the netbook screen with this script (arandr script):

$ xrandr --output VGA1 --off --output LVDS1 --mode 1024x600 --pos 0x0
--rotate normal

When i start, there are no problems.

After i change screen whith this script:

$ xrandr --output LVDS1 --off --output VGA1 --mode 1440x900 --pos 0x0
--rotate normal

Most of the time my vga screen is black with just the mouse pointer.
And when i want go to the netbook screen, with the first script, most of
the time my LVDS screen is black.
I use Ctrl+Alt F8 and Ctrl+Alt F7 to have a normal output.

Since i change the fisrt script and the second one like this, my
problems are solved :

The first:
$ xrandr --output VGA1 --off
$ xrandr --output LVDS1 --mode 1024x600 --pos 0x0 --rotate normal
The second:
$ xrandr --output VGA1 --mode 1440x900 --pos 0x0 --rotate normal
$ xrandr --output LVDS1 --off

Thank you.
Goodbye.
