Is the resolution OK if you login to KDE? Was the monitor switched on when 
the xserver started? What graphics card is in that machine?

If the resolution is wrong for your KDE session as well, you could switch 
to a text console using the shortcut Ctrl-Alt-F1 and login. Then use 
these commands:

sudo /etc/init.d/kdm stop
sudo dpkg-reconfigure xserver-xorg
sudo /etc/init.d/kdm start

If you use gdm, replace "/etc/init.d/kdm" with "/etc/init.d/gdm" for the 
commands above. These commands might repair the problem, but if your 
graphics card is not really supported, like e.g. some older ATI cards, 
that will not help.
