Nowadays, this file can be empty. Everything 'should' be auto-detected.

Ah, you already knew the location of the file?

Your resolution is limited to the horizsync and vertrefresh in the monitor 
section. Look up the values in the manual of your monitor. (Some old 
videocards will limit resolution too. You didn't say what card you have, but 
it's probably not such a old one.)

Section "Monitor"
	Horizsync		??-??
	VertRefresh	??-??
EndSection

Again, this should be automatically detected.

Well, you mentioned something, but not what the problem was. An off-center 
resolution could be because your virtual resolution is not the same as the 
monitor resolution.

Now, because we're talking about KDE you could try the following. You didn't 
say what version of Kubuntu you are using, so I will assume you have KDE 4.x
- Delete /etc/X11/xorg.conf
- Set the resolution in 'System Settings --> Display'. (this actually uses 
xrandr)
If this doesn't work, either your hardware is faulty (a lot of monitors do not 
report their values correctly), or there is a bug somewhere.
