[Grml] graphic login on tty7

[Dietmar Segbert]

Hello,

i have installed grml on my netbook. I use grml with speakut an brltty.
Now i have installed the gnome-desktop with orca.

Normally i want to use the textconsoles tty1 to tty6 and start gnome- 
desktop with startx.

So my question:

How must i modify grml, so that i have six textconoles an  ont tty7 a  
graphical login (gdm3), so that ic can change with ctrl+alt+f(x) between  
the consoles?

Tanks for your help.

Regards.

Dietmar
