Unhappy nvidia xorg resolution problem

I have dual boot system winXp and Kubuntu 9.04
my video card is a 8800 GTS that work fine in windows
and this video card was also working fine in linux but
now it simply refuse to set the appropriate screen resolution 1920x1200
my display is a SamSung SyncMaster 2443bw.

below are some logs:
the resolution always fall to 640x480
I have 2 video card for the 7900 when I try it I can load the "nv" driver.. but as for the 8800 GTS not even the "nv" driver will load

Since the same card is doing fine under windows I don't suspect that I have a faulty card nor a falty display..

Thanks for any help..

Check if you have the nvidia-settings program. See if you can change the resolution and save the settings. If you don't have an /etc/X11/xorg.conf file, try the nvidia-xconfig program first to create an initial xorg.conf file.

Another thing to try is using the GTF program.
gtf 1920 1200 60 x

Remove the ".00" from the label of the modeline printed out. Then if your xorg.conf file, if you have a "Modes" section, add it to that. If not, you can add it to your "Monitor" section. Then add the mode to your "Screen" subsections. The label will probably look like "1920x1200@60". Add that to the modes lines in the "Screen" subsections.

For example:
Code:
Section "Screen"
  DefaultDepth 24
  SubSection "Display"
    Depth      15
    Modes      "1920x1200@60" "1440x900" "1366x768" "1360x768" "1280x800" "1152x864" "1280x768" "1280x720" "1024x768" "1280x600" "1024x600" "800x600" "768x576" "640x480"
  EndSubSection
Also make sure that your horizontal and vertical refresh settings are within your monitors ratings.

Here is my xorg.conf...
is it possible that my screen of my video card might develop a problem that only arise in Linux ... I'm worried about that line in the log files

fwiw, I had to jump through some hoops to get the resolution I wanted that was in conflict with edid and declared invalid by Xorg.

I found cvt to work better and needed the -r switch; see man cvt

Code:
$ cvt -r 1280 800                                     
# 1280x800 59.91 Hz (CVT 1.02MA-R) hsync: 49.31 kHz; pclk: 71.00 MHz    
Modeline "1280x800R"   71.00  1280 1328 1360 1440  800 803 809 823 +hsync -vsync
I only really use/need the one resolution but there are others in my xorg.conf:

Code:
Section "Monitor"
    Identifier "monitor1"
    HorizSync 30.0 - 81.0
    VertRefresh 56.0 - 75.0

I found that, if there was a higher resolution mode, xorg loaded that, so I made sure mine was the highest, removed the rest.

There was an option I needed in the "Device" section in order for my unorthodox mode to get loaded:

Code:
Section "Device"
    Identifier "Device0"
    VendorName "NVIDIA Corporation"
    BoardName "GeForce 9500 GT"
    Driver "nvidia"
    Option "ExactModeTimingsDVI" "yes"
#    Option "UseEDIDFreqs" "false"
#    Option "ModeValidation" "DFP-1: NoMaxPClkCheck, NoEdidMaxPClkCheck, AllowNon60HzDFPModes"
EndSection
Option "ExactModeTimingsDVI" "yes"
was necessary. I found it in the documentation that comes with the nvidia driver. The commented options might have worked once but switches get dropped, or they might just have been experimental failures.

Thanks for the help... for now I can get my normal screen resolution by changing my cable form the DVI connection to the VGA connector not sure the reason why but for now it work... I have try the option you included in your response.. the Option "ExactModeTimingsDVI" "yes" this just turn my screen black.. I guess what I need to do now if to find out why the DVI connector in not working in linux because this works fine in with my WindosXP...

I found now that I can't save the current configuration with nvidia-settings ..the application always return tha he cannot parse the xorg.conf file..

thanks again.
