x don't start in debian

[erkko . lahnajarvi]

Hello,

I installed debian 3.1r4 debian on my PC, which has 1Ghz amd duron 
processor. Then I executed commands:

aptitude install xfree86-common
and it seemed to be installed

aptitude install xserver-xfree86
and it seemed to be installed too

after these two commands I wrote start X in command prompt in all 
possible forms(startx, start X, startX, start x),but

...tadaa, it didn't start any graphical interfece
