I did some research and found information on the devise setup but do not know how to do three heads on one desktop ( or two tty, one normal desktop and another for mythTV).
Code:
 Option       "SecondMonitorHorizSync" "30-50"
        Option       "SecondMonitorVertRefresh" "60"
        Option       "TVStandard" "PAL-B"
        Option       "TVOutFormat" "COMPOSITE"
        Option       "RenderAccel" "true"
Any help would be greatly appriciated.
