LCD a obnovovaci frekvence monitoru?

[bambas]

Zdravim,
vymenil jsem CRT monitor za LCD. Mam ovsem problem, bezi mi na 70Hz, co 
nechci, rad bych snizil na 60Hz. Vyhledal jsm na netu nejake informace, 
podle tech vypocital Modeline a pridal do xorg.conf. Jenze po pridani 
radku Modeline mi X sevrer hlasi chybu No screens found a Xka 
nenastartuji. Kde delam chybu? Zasilam svuj xorg.conf

diky bambas
