Followup - How is ModeLine chosen?



Thans to all who responded. I found out about xvidtune - so I used it
to inquite about the pixel clock and sync and it reports exactly the
right figures. What's interesting is that it reports the pixel clock at
"108" regardless of whether or not the following modelines are present
in the XF86Config file: 

"Picks" this one:
#Modeline "1280x1024"  108    1280 1328 1512 1712  1024 1025 1028 1054
etc...
#Modeline "1280x1024"  108.5    1280 1328 1512 1712  1024 1025 1028
1054
#Modeline "1280x1024"  109    1280 1328 1512 1712  1024 1025 1028 1054
#Modeline "1280x1024"  109.5    1280 1328 1512 1712  1024 1025 1028
1054
This is a line originally made by Xconfigurator before I switched to
the lat panel and nvidia driver (Xconfigurator does not work with the
nvidia driver):
Modeline "1280x1024"  110    1280 1328 1512 1712  1024 1025 1028 1054
Modeline "1280x1024"  126.5 1280 1312 1472 1696  1024 1032 1040 1068
...

I'm not sure whay my display was looking bad in the first place - I
think the flat panel (MAG LT765S) is successfully communicating that it
needs exactly a 108 pixel clock and 63.98 Horiz and 60.02 Vert to look
best. The display has an "autotune" and "phase" adjustment - fiddling
with these usually makes things look worse.

So, in summary, the XF86Config modelines seem to be ignored, at least
for fine tuning the pixel clock, if the driver can get the info it
needs form the monitor.
