12.10 low screen resolution problem

I have successfully repaired my nvidia driver issue so that the driver is loaded correctly.

Within nvidia-settings I can set up my desktop to meet my needs (2 displays both at 1920x1080, twinview).

After configuring and checking that the displays was set correctly, i clicked save to x configuration file

Xorg.conf looks like:

Section "ServerLayout"

    Identifier     "Layout0"

    Screen      0  "Screen0" 0 0

    InputDevice    "Keyboard0" "CoreKeyboard"

    InputDevice    "Mouse0" "CorePointer"

    Option         "Xinerama" "0"

EndSection

Section "Monitor"

    # HorizSync source: edid, VertRefresh source: edid

    Identifier     "Monitor0"

    VendorName     "Unknown"

    ModelName      "Ancor Communications Inc ASUS VW247"

    HorizSync       30.0 - 80.0

    VertRefresh     50.0 - 75.0

    Option         "DPMS"

EndSection



Section "Device"

    Identifier     "Device0"

    Driver         "nvidia"

    VendorName     "NVIDIA Corporation"

    BoardName      "GeForce GTX 660 Ti"

EndSection



Section "Screen"

    Identifier     "Screen0"

    Device         "Device0"

    Monitor        "Monitor0"

    DefaultDepth    24

    Option         "Stereo" "0"

    Option         "nvidiaXineramaInfoOrder" "DFP-0"

    Option         "metamodes" "DFP-0: 1920x1080 +0+0, DFP-3: 1920x1080 +1920+0"

    SubSection     "Display"

        Depth       24

    EndSubSection

EndSection

So I assume that the 1920x1080 resolution is correctly saved to xorg.conf.
But, if I now restart my PC or logout/login, I get both monitors to 1024x768.

If I then go to nvidia-settings again I can configure it successfully again to be working at 1920x1080.

So I think the driver is ok because the resolution is configureable and works as expected, but during boot it does not load the correct values.

How can I tell my system to use the high resolution during boot?

Your config file seems to be missing info. This can happen because Xorg no longer uses the config file in the same way.

If your nvidia drivers are working fine then start by removing all sections except "device". Make sure to backup the file first of course.

Once X comes back up use Displays (from the dashboard or system setting) to correct the resolution. This will save the setting so that it is "high res" whenever you log in.

Make sure, the first time you make the changes, to actually log out, and not just kill X or issue the reboot command.

It that doesn't work for you you can try editing your settings in Nvidia Settings and saving them to the Xorg config file, but this should not be needed.

Basically the Xorg config structure underwent a huge change a few years ago and now a lot of the well published data is just plain wrong, or leads you down the wrong path. Simply put the Xorg config file should only be used to override things that don't work normally.
