Hi Yann,

Thanks for the quick response!  I'll have to go home and look at the screen
to be sure, but I don't think it worked.  When I added the modeline to my
xorg.conf, and restarted, I saw the following in my xorg.0.log file:

****
(--) NVIDIA(0): Connected display device(s) on GeForce FX 5200 at PCI:1:0:0:
(--) NVIDIA(0):     NVIDIA TV Encoder (TV-0)
(--) NVIDIA(0):     Philips FTV (DFP-0)
(--) NVIDIA(0): NVIDIA TV Encoder (TV-0): 350.0 MHz maximum pixel clock
(--) NVIDIA(0): TV encoder: NVIDIA
(II) NVIDIA(0): Assigned Display Device: DFP-0
(WW) NVIDIA(0): No valid modes for "1024x768"; removing.
(WW) NVIDIA(0):
(WW) NVIDIA(0): Unable to validate any modes; falling back to the default
mode
(WW) NVIDIA(0):     "nvidia-auto-select".
(WW) NVIDIA(0):
(II) NVIDIA(0): Validated modes:
(II) NVIDIA(0):     "nvidia-auto-select"
(II) NVIDIA(0): Virtual screen size determined to be 1280 x 720
****

The modeline was added to my monitors section as follows.  The commented
lines are failed attempts thus far.

[code]
Section "Monitor"
        Identifier   "Monitor0"
        VendorName   "Unknown"
        ModelName    "Unknown"
#       HorizSync    30.0 - 110.0
#       VertRefresh  50.0 - 150.0
        HorizSync 42.0 - 52.0
        VertRefresh 55.0 - 65.0
# Modeline generated by http://bohne-lang.de/spec/linux/modeline/
        Modeline "1024x768" 60.80  1024 1056 1128 1272   768  768  770  796
# Modeline generated by gtf from localhost
#       Modeline "1024x768_60"  64.11  1024 1080 1184 1344  768 769 772 795
-HSync +Vsync
        Option      "DPMS"
EndSection
[code]

And I don't really know what the "NVIDIA TV Encoder (TV-0)" device is.  Can
anyone tell me?  I'm interested, because that device is reported as a
secondary display in the nvidia-settings gui - with a max resolution of
1024x768.  Maybe I need to find some way to swap that to be my primary
display?

Thanks!
