    Question GDM = wrong resolution/refresh rate

    I'm using ubuntu 8.10, I've setup an automatic login, however it still pops up during boot with a brown square that is off centered. This is because it is using another resolution/refresh rate independent of what is setup once you login. (I tried without an automatic login and the login displays similarly to that brown square off center on the screen)

    In ubuntu 8.10 how does one setup a machine to display the same resolution and refresh rate on the login as compared to the settings within ubuntu.

    Yes I've searched several times for several different machines that this occurs on but I've never found anything concrete.
    If somebody could please explain why this behavior exists that be great too.

    As well my xorg.conf is completely blank, should I be concerned.

    Thank you for any help/advice.

    xorg.conf has been slimmed down by default but it still can be used to set monitor display settings

    this command should give you all the xorg.conf questions instead of the new slimmed down one.

    Code:
    sudo dpkg-reconfigure -phigh xserver-xorg
    You can mannually edit xorg.conf too.
    After either of theses steps it should look like this

    # THIS IS FOR MY 20" G5 iMAC - change accordingly!
    # FPDithering is only for nv driver and lcd screens

    Section "Monitor"
    Identifier "Configured Monitor"
    HorizSync 28-84
    VertRefresh 43-60
    EndSection

    Section "Screen"
    Identifier "Default Screen"
    Monitor "Configured Monitor"
    Device "Configured Video Device"
    DefaultDepth 24
    SubSection "Display"
    Depth 24
    Modes "1680x1050"
    EndSubSection
    EndSection

    Section "Module"
    Disable "glx"
    Disable "dri"
    EndSection

    Section "Device"
    Identifier "Configured Video Device"
    Driver "nv"
    Option "FPDither" "true"
    EndSection
    The important part is

    Section "Monitor"
    Identifier "Configured Monitor"
    HorizSync 28-84
    VertRefresh 43-60
    EndSection

    Section "Screen"
    Identifier "Default Screen"
    Monitor "Configured Monitor"
    Device "Configured Video Device"
    DefaultDepth 24
    SubSection "Display"
    Depth 24
    Modes "1680x1050"
    EndSubS
    Wait, yes I am but my point remains valid!
