Here is what I have found ... For me, now it fully works... Try with this modeline in the monitor section: Modeline "1440x900" 129.73 1440 1480 1616 1848 900 903 906 936 -HSync -VSync and with this device section: BusID "PCI:0:16:0" Option "DPMS" Option "FlatPanel" "true" Option "CrtcNumber" "0" Thanks for the Anonymous at TUXPPC Forum who post this !!!!
