[solved] 1440x900 resolution

Well I just picked up a new monitor.  It's an LG Flatron 18.9" and I'm pretty happy with it, but I can't get X to run in 1440x900 screen resolution.I've been searching and trying different things for a couple hours now and just can't seem to get anything but 1280x1024.

lspci says: VGA compatible controller: ATI Technologies Inc RV350 AS [Radeon 9550]

My xorg.conf is as follows:

Section "ServerLayout"
        Identifier     "Xorg Configured"
        Screen      0  "Screen0" 0 0
        InputDevice    "Keyboard0" "CoreKeyboard"
        InputDevice    "PS/2 Mouse" "CorePointer"

        SubSection "Display"
                Depth     24
                Modes "1440x900"
        EndSubSection
EndSection

Section "DRI"
        Mode 0666
EndSection

Section "ServerFlags"
        Option "DontZap" "false"
EndSection

I did at one point have:
Section "Screen"
        Identifier "Screen0"
        Device     "Card0"
        Monitor    "Monitor0"
        DefaultColorDepth 24
        SubSection "Display"
                Virtual 1440 900
                Depth     24
                Modes "1440x900"
        EndSubSection
EndSection

But when I restarted X everything was garbled.  I had to ctrl+alt+backspace and remove Virtual 1440 900 to get things so I could see what I was doing again.

I've also run xrandr -s 1440x900 and it replies:
Size 1440x900 not found in available modes

Help would be greatly appreciated!

Re: [solved] 1440x900 resolution

what if you don't use the vesa video driver? or did you try that already?
Did your old monitor get 1440x900?

I switched to the open source ati driver and everything works fine.  I can't believe I didn't try that in the first place.  Thanks!
