Debian Etch can not startx

[rocky <rocky2winnie@gmail.com>]

Hey,

I got a very old PC which was purchased 6 years ago. I use Debian
netinstall CD installed the base Debian etch system. I have been
trying to install basic GUI on it. Therefore I execute the following
command:[QUOTE]#aptitude update
aptitude install twm x-window-system[/QUOTE]

I was asked for some questions regarding to my hardware. I was not
quite sure whether my answer is right because I'm quite new to
computer hardware and I have no means to find the manuals for the old
PC.

After that the startx gave me the following errors

I was trying dpkg-reconfigure xfree86 but it seems this does not bring
me the interfaces where I can reconfigure my x-window-system.

Can any of you give me some hint on how can I get over these problems
please?

Thanks a lot in advance!
