    Re: Relsolution problem

    What is the video h/w model ?
    Is there a reason for running a really old nvidia driver ?

    How is your newly bought monitor connected ? DVI is preferred.

    It is easier to get the monitor correctly identified by EDID than it is to add custom modes or force modes..so you should try that first..

    You could post your
    /var/log/Xorg.0.log
    file as an attachment to help answer some of the above..

    EDID is the data that identifies the display device & exposes its capabilities.

    The VGA standard includes I2C interface (DDC) that allows video card to probe the displays eeprom for model & video mode info (even if powered down).

    DVI does the same.
    HDMI achieves something similar & for audio ELD only when power is on.

    You are right about the driver version & MX440..

    From your log file:
    Monitor is identified & no video mode is requested..auto is selected & driver uses 1024x768..
    so all is okay..

    This is a TV styled display , any 19" PC display would have at least 1440x900.
    It is possible the VGA input will not accept native resolutions.--I have checked the specs, VGA should work.

    I would not recommend buying any DFP monitor without DVI/displayport/hdmi.

    You are trying to use the nvidia-settings program to set the resolution ?
    Do you have the option of 1368x768 ?


    The video mode 1366x768 is not a std mode.. 1368x768 is std mode.. 1366 is not divisible by eight.
    The modeline calculator "cvt" will not calculate a 1366 modeline...

    from cvt calculator , add these sections to /etc/X11/xorg.conf file by including the existing..
    Code:
    Section   "Modes"
              Identifier       "CustomModes"
              Modeline     "1368x768_60.00"   85.25  1368 1440 1576 1784  768 771 781 798 -hsync +vsync
    EndSection
    
    Section    "Monitor"
              Identifier         "Monitor0"
              VendorName       "Viewsonic"
              ModelName        "VA ----"
              UseModes           "CustomModes"
              Option             "DPMS"
    EndSection
    
    Section Screen 
              Identifier         "Screen0"
              Device             "Device0"
              Monitor            "Monitor0"   
    # add this 
          SubSection        "Display"
                       Depth        24
               Modes          "1368x768_60.00"
          EndSubSection
    EndSection
    from XFree86 modeline calculator
    gives 1360 or 1368 .. will not accept 1366

    If you need to force a 1366x768 modeline it could be possible, it depends on the driver accepting the numbers.

    Cool Re: Relsolution problem

    Hello ,

    The changes i made fixed the back log-in screen but once i log in its still the wrong size with no Gnome panel from the X.org log :

    Code:
    [    86.553] (WW) NVIDIA(0): No modes were requested; the default mode "nvidia-auto-select"
    [    86.553] (WW) NVIDIA(0):     will be used as the requested mode.
    [    86.553] (WW) NVIDIA(0): 
    [    86.553] (II) NVIDIA(0): Validated modes:
    [    86.553] (II) NVIDIA(0):     "nvidia-auto-select"
    [    86.554] (II) NVIDIA(0): Virtual screen size determined to be 1024 x 768
    [    86.554] (--) NVIDIA(0): DPI set to (63, 84); computed from "UseEdidDpi"
    I how i stop the driver from Checking which modes to use ??? I've attached the log and the config

    Re: Relsolution problem

    The driver seems to be ignoring the screen section completely..
    The xorg.conf layout is as per the Xorg defining docs X11R6 & is as I have used with nvidia 173 to 260.
    Maybe the earlier nvidia driver did not follow the standard or I have not understood.

    There is a shortcut syntax for sticking the modeline directly into "Monitor" section.
    Maybe that will work...just copy the modeline (one line) into the monitor section.

    From re-reading this thread...
    You can not use the Gnome Display preferences with the nvidia X server..
    You must only use the nvidia-settings programs, the Gnome tools do not correctly recognize the video modes/refresh rates.

    Hello BicyclerBoy,

    Thanks for your help so far ! It does not come up in the Nividia settings but in the monitor settings if i apply it from the monitor settings and reboot i get an error saying the X sever does not support the mode.


    I will make the changes to the config and report back ! ( Yes i will need to force it )

    Hello BicyclerBoy,

    The config file was blank so I ran sudo Nvidia-xconfig once i'd rebooted the gnome Panel had gone so remove nvidia 96 and this fixed this. I removed everything the nvidia-xconfig command put and add what you said but i get the following error :

    Re: Relsolution problem

    Whoops..

    The error reports that there is "an unquoted string" on line 14 of xorg.conf.
    The screen section should have started
    Section "Screen"

    i.e. "Screen" keyword must be quoted...

    You can do a console login ...
    enter username & password when prompted..

    you could make a backup of xorg.conf & then delete it..
    re-run nvidia-xconfig

    Or..
    sudo nano /etc/X11/xorg.conf

    edit line 14...& add the missing ("").


    Maybe you could post your xorg.conf file so I can try to add the extra sections..
