I have an NVidia GEforce 7200 family card. When installing the (then-) current driver (NVIDIA-Linux-x86_64-100.14.19), I could not get it to go 1680x1050.


  • in the display applet, select "LCD Panel 1680x1050"
  • exit from, and stop X (ie run init 3)
  • edit /etc/X11/xorg.conf
  • locate the Section "Monitor" for the LCD Panel 1680x1050
  • edit the HorizSync to be 30.0 - 83.0
  • edit the VertRefresh to be 56.0 - 75.0
  • your section should look like this:
Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "Unknown"
        ModelName    "LCD Panel 1680x1050"
        HorizSync    30.0 - 83.0
        VertRefresh  56.0 - 75.0
        Option      "DPMS"
  • find the Section "Screen" that describes the video mode
  • add "1680x1050" to the beginning of the video mode list, it will look like this:
Section "Screen"
        Identifier "Screen0"
        Device     "Device0"
        Monitor    "Monitor0"
        DefaultDepth     24
        SubSection "Display"
                Depth     24
                Modes    "1680x1050" "1400x1050" "1280x1024" "1280x960" "1024x768" "800x600" "640x480"
  • save, test with startx, if happy exit out of it and run init 5 to restart the graphical environment.

This is a collection of techical information, much of it learned the hard way. Consider it a lab book or a /info directory. I doubt much of it will be of use to anyone else.
