Yeah, something is changing the resolution back to 1024x768
I would add the following to your system:
In the "Monitor" section add:
Option "ExactModeTimingsDVI" "True"
Option "UseEDIDFreqs" "False"
In the "Screen" section add:
Option "FlatPanelProperties" "Scaling = Native"
In the "Device" section add if using VDPAU:
Option "HWCursor" "false"
So your xorg.org becomes:
Section "ServerLayout"
Identifier "Layout0"
Screen 0 "Screen0" 0 0
InputDevice "Keyboard0" "CoreKeyboard"
InputDevice "Mouse0" "CorePointer"
Option "Xinerama" "0"
EndSection
Section "Files"
EndSection
Section "InputDevice"
# generated from default
Identifier "Mouse0"
Driver "mouse"
Option "Protocol" "auto"
Option "Device" "/dev/psaux"
Option "Emulate3Buttons" "no"
Option "ZAxisMapping" "4 5"
EndSection
Section "InputDevice"
# generated from default
Identifier "Keyboard0"
Driver "kbd"
EndSection
Section "Monitor"
Modeline "1440x900_60" 106.50 1440 1528 1672 1904 900 903 909
934 -hsync +vsync

VertRefresh 60.0 - 75.0
Option "DPMS"
Option "DPI" "96 x 96"
Option "ExactModeTimingsDVI" "True"
Option "UseEDIDFreqs" "False"
Option "ExactModeTimingsDVI" "True"
Option "UseEDIDFreqs" "False"
EndSection
Section "Device"
Identifier "Device0"
Driver "nvidia"
VendorName "NVIDIA Corporation"
BoardName "ION"
Option "CustomEDID" "DFP-0:/etc/X11/tv-edid.bin" #Force a
custom EDID.
Option "UseDisplayDevice" "DFP-0"
Option "ConnectedMonitor" "DFP-0"
Option "ModeDebug" "True" #This will turn up logging in
the /var/log/Xorg.0.log file.
Option "HWCursor" "false"
EndSection
Section "Screen"
Identifier "Screen0"
Device "Device0"
Monitor "Monitor0"
DefaultDepth 24
Option "FlatPanelProperties" "Scaling = Native"
Option "TwinView" "0"
SubSection "Display"
Depth 24
Modes "1440x900_60"
EndSubSection
EndSection
If your custom modeline is good, you should get a picture now.
