LG L226WTY on CentOS 4.5

Problem

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.

Solution

• 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"
EndSection

• 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"
        EndSubSection
EndSection

• save, test with startx, if happy exit out of it and run init 5 to restart the graphical environment.
