This is the monitor section of my XF86Config file:
Code:
Section "Monitor"
Option "CalcAlgorithm" "CheckDesktopGeometry"
HorizSync 27-85
Identifier "Monitor[0]"
ModelName "6556 P72"
VendorName "IBM"
VertRefresh 50-150
UseModes "Modes[0]"
EndSection
The HorizSync and VertFresh lines (in bold) are the ones you want to change.Be sure you dont enter a refresh rate greater than the one your monitor is rated at or it's goodbye monitor
If it looks different it's because I use the SuSE 8.1 on this computer.
The next time the screen goes blank and you have a cursor showing,hit the keys ctrl-alt-backspaceinstead of turning the power off.That keyboard combo restarts the x-server.
HTH
