I have a question about the XF86Config-4 file. How can so many "modeline" options exist in the one configuration file? How does the computer deal with them?
I mean take an example
# 800x600 @ 60Hz (VESA) hsync: 37.9kHz
ModeLine "800x600" 40.0 800 840 968 1056 600 601 605 628 +hsync +vsync
I have about 20 to thirty of these in XF86Config-4, all giving different parameters.
Sure, the resolution line has a hash, so that means it's ignored? So maybe it's a comment. But the modeline is not hashed, so what does the com¨ter do with so many of them?
Surely, for optimimum performance, we should be specifying just one modeline for our monitor...
I ask all this without really knowing what a modeline does ... so if you know, pelase tell.
