Hmmm...
Well, this is what my X log says:
(II) NVIDIA(0): NVIDIA GPU GeForce4 MX 4000 at PCI:0:9:0
(--) NVIDIA(0): VideoRAM: 65536 kBytes
(--) NVIDIA(0): VideoBIOS: 04.18.20.39.07
(--) NVIDIA(0): Interlaced video modes are supported on this GPU
(--) NVIDIA(0): Connected display device(s) on GeForce4 MX 4000 at
PCI:0:9:0:
(--) NVIDIA(0): NVIDIA TV Encoder (TV-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: TV-0
(WW) NVIDIA(0): No valid modes for "720x480_60"; removing.
(WW) NVIDIA(0): No valid modes for "NTSC_60i"; removing.
(WW) NVIDIA(0):

(WW) NVIDIA(0):

(II) NVIDIA(0): Virtual screen size determined to be 1024 x 768
It apparently doesn't like my modelines and modes. Here is a snippet from
my xorg.conf...
Section "Monitor"
Identifier "Monitor0"
VendorName "Monitor Vendor"
ModelName "27in Analog TV"
HorizSync 30.0 - 50.0
#VertRefresh 60.0 - 60.0
Option "dpms"
Option "UseEdidDpi" "FALSE"
Option "DPI" "100 x 100"
ModeLine "NTSC_60i" 14.318 768 784 848 910 483 484 492 525 Interlace
Modeline "720x480_60" 26.72 720 736 808 896 480 481 484 497
-HSync +Vsync
EndSection
I got the first Modeline from the MythTV modeline page in Wiki and the
second was generated by gtf.
Then I use them as follows:
Section "Screen"
Identifier "Screen0"
Device "Videocard0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 24
# #Modes "1024x768_60" "800x600_60" "640x480_60"
# #Modes "800x600_60" "640x480_60"
Modes "720x480_60" "NTSC_60i"
EndSubSection
EndSection
Can anybody see why these should be rejected? Remember, I'm outputting to a
TV, not a monitor.
