Ok, I'll admit I'm not much of a genius when it comes to modifying
xorg.conf.  Every time I get a newish piece of hardware I am reminded
of this.

My setup includes a Biostar board with an onboard nVidia Geforce 8200.
 My LCD is an Acer 22" with native resolution of 1400x1050.  Distro is
Debian Lenny, if that matters.

Whenever I get into a bind with my xorg.conf, I pop in Knoppix to let
its auto-configurator tool generate me a nice xorg.conf.  Then I take
and modify that for my system, as Knoppix doesn't always pick the best
settings, but they at least work and give me a template to start
hacking.

I want to add 1400x1050 as a resolution, but for some reason it just
won't accept it.

        SubSection "Display"
                Depth     16
                Modes "1600x1200" "1400x1050" "1280x1024" "1024x768"
"800x600" "640x480"

Defaults to 1600x1200 when I start X (duh).
If I remove the 1600x1200 line:

        SubSection "Display"
                Depth     16
                Modes "1400x1050" "1280x1024" "1024x768" "800x600" "640x480"

It defaults to 1280x1024.  I have Modelines configured for 1400x1050:

        ModeLine "1400x1050"  122.61  1400 1488 1640 1880  1050 1051
1054 1087  -HSync +Vsync
        ModeLine "1400x1050"  149.34  1400 1496 1648 1896  1050 1051
1054 1094  -HSync +Vsync
        ModeLine "1400x1050"  155.85  1400 1496 1648 1896  1050 1051
1054 1096  -HSync +Vsync
        ModeLine "1400x1050"  179.26  1400 1504 1656 1912  1050 1051
1054 1103  -HSync +Vsync
        ModeLine "1400x1050"  214.39  1400 1512 1664 1928  1050 1051
1054 1112  -HSync +Vsync

But no go.

Any ideas?  I've posted my xorg.conf on Pastebin:  http://pastebin.com/m4db91abc

Thanks,
