Looks like you chose the wrong driver for your card (the vga driver).
Try

dpkg-reconfigure xserver-xfree86

and choose the right one. Take a look at the documentation on
<http://www.xfree86.org> to find out if you don't know. Debian 3.0
(Woody) comes with XFree 4.1 (and also 3.3.6). You can also try the
vesa driver, which should work with all modern cards.

You cannot run Gnome if your X server does not startup.

gdm is a graphical login manager. You don't want to start gdm if you are
already logged in, instead you want to start Gnome. However, neither
Gnome or gmd can be used if your X server does not work. And because
the system probably tried to load gdm at boottime, but loading was not
finished because your not-working X server, the system /thinks/ it is
running.

Thank you for your help. I have a card wich is not supported by the
xserver, so I had to download the driver. It works now.
