Well didn't know what happened :-)
Guess the RAMS didn't emptying itself at first, but today when I
want to solve to "X aborting" thing, the Gnome suddenly appear on the
screen :-D
Oh boy !!!!!!
This is what have wanted for so long !
Debian on my own box !!!
The installation was a breeze, actually I just had to hit "Enter" all
the way except when user and passwords had to be typed in and space
when I had to select some choices. All the way the installer did find
the right hardware etc.
For a start I had to write "installgui" at the boot prompt. The
GUI-installer is very nice except for some translation errors US > DA
(grrr).
