[Xpert]How is modeline chosen?

2002-10-15 Thread Spammers Must Die 

I just got my new 1280x1024 17 flatscreen set up, and
it looked like hell, with moires, aliased vertical
lines, etc.. As seems to be the case after running
XF86Config originally, I had several 1280x1024 
ModeLines in my XF86Config file. The closest modeline
looked like this:

# 1280x1024 @ 61 Hz, 64.2 kHz hsync
Modeline 1280x1024 110 1280 1328 1512 1712 1024 1025
1028 1054

Since the flat screen really wants to have *exactly*
the right pixel
frequency, as a shot in the dark I added these lines
right above that
one:
Modeline 1280x1024 108 1280 1328 1512 1712 1024 1025
1028 1054
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

I changed only the pixel clock - it's close enough
that the other
parameters didn't seem to need adjustment - and things
look very good now.. 
right now my display says it's getting 63.9 kHz
horzontal sync - almost 
perfect. (The display wants 63.98 H and 60.02 V.)

My question is: In the presence of several 1280x1024
modelines, how is 
the modeline chosen? Is XF86 even using the XF86Config
file? The 
XF86COnfig-4 files doesn't have any modelines in it. I
don't see 
anything in the log file except (II) NVIDIA(0):
Setting mode 1280x1024

This is XFree86 4.2.0, the one that comes with RedHat
7.3, and the 
NVidia-supplied driver to a Geforce2.

Thanks,

You can toggle trough multiple modes with 
same resolution by naming them differently.
Those ... labels are (freeform?) strings.
This means you can e.g. have a 640x480i
and a 640x480p timing, where the appended
characters might mean for your individual setup 
interlaced and progressive mode.


The real desktop resolution is encoded in the numeric data.
