Hi!
I couldn't find any obvious issues in the nvidia-bug-report.log, however the
following hints might be useful:
The log output of the X server says:
Code:
(II) NVIDIA(0): NVIDIA GPU Quadro FX 3500 (G71GL) at PCI:24:0:0 (GPU-0)
[...]
(--) NVIDIA(0): HP 2025 (DFP-0): 330.0 MHz maximum pixel clock
(--) NVIDIA(0): HP 2025 (DFP-0): Internal Dual Link TMDS
(--) NVIDIA(0): HP 2025 (DFP-1): 330.0 MHz maximum pixel clock
(--) NVIDIA(0): HP 2025 (DFP-1): Internal Dual Link TMDS
[...]
(II) NVIDIA(GPU-1): NVIDIA GPU Quadro FX 3400 (NV40GL) at PCI:88:0:0 (GPU-1)
[...]
(--) NVIDIA(GPU-1): HP 2025 (DFP-1): 155.0 MHz maximum pixel clock
(--) NVIDIA(GPU-1): HP 2025 (DFP-1): Internal Single Link TMDS
Some product spec says that the FX3400 has one Dual-Link DVI output and
one Single-Link DVI output. So it looks like you have attached the third LCD to
the SL DVI output. There's basically nothing wrong about that, because a
1600x1200 LCD should work with a single link connection, too, but for the sake
of completeness, you may try if using the other output on the FX3400 makes
any difference.
BTW.: I used to put the Option "Xinerama" "True" (rather than "1") into the ServerLayout
section (rather than into ServerFlags), but i guess it should work the way you have
it, too.
In the ServerLayout, it says:
Code:
Screen 0 "Screen0" 0 0
Screen 1 "Screen1" 1600 0
Screen 2 "Screen2" RightOf "Screen1"
That should work, but in case you once change the displays
with different resolution, then the fixed 1600 0 might be a problem.
I'd rather use this to make it independent from the screen
resolution:
Code:
Screen 0 "Screen0" 0 0
Screen 1 "Screen1" RightOf "Screen0"
Screen 2 "Screen2" RightOf "Screen1"
There are metamodes defined in each screen section. You shouldn't
need them for your setup.
