Problem with 1440x900 resolution with ATI card

I can't turn my resolution to 1440x900.

When i start X in 1440x900 i see a big black bar at left side. I have tried with many modelines for my monitor, but with no result.

lspci | grep VGA:

04:00.0 VGA compatible controller: ATI Technologies Inc RV370 5B60 [Radeon X300 (PCIE)]

xorg.xonf:

Section "Monitor"
        Identifier   "X193W"
        Option      "DPMS" "true"

#        HorizSync    30.0 - 82.0
 #       VertRefresh  50.0 - 75.0
       ModeLine     "1440x900" 141.9 1440 1512 1688 2008 900 900 903 942
        Option      "DPMS"

EndSection

Section "Device"
        Identifier  "Card0"
        Driver      "fglrx"

        BusID       "PCI:4:0:0"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        Monitor    "X193W"
        Defaultdepth    24
        SubSection "Display"
                Modes           "1440x1440"     "1440x900"      "1280x1024"     "1024x768"      "832x624"       "800x600"       "720x400"       "640x480"
        EndSubSection

EndSection

Section "DRI"
        Mode         0666
EndSection

Re: Problem with 1440x900 resolution with ATI card

I don't have the same monitor but try removing Section "Monitor" and your modelines.  They should be auto detected with the latest X.org

Try this:

Section "Device"
        Identifier  "Card0"
        Driver      "fglrx"
        BusID       "PCI:4:0:0"
EndSection

Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        Monitor    "X193W"
        Defaultdepth    24
        SubSection "Display"
                Depth     24
        EndSubSection

EndSection

Section "DRI"
        Mode         0666
EndSection

A good rule with modern X is to only define the things you need to change/fix.
