Alan,

I found ESR's VideoModes.doc to be very helpful.  You can find it in the XFree86
cvs tree, or google it.

Subject: How do you know? (Was: Setting Vertical refresh)


I have a basic question: how do you know it when the vertical refresh is the
problem and not, for example the horizontal refresh?

I have an old computer that I have not dug into X windows configuration yet.
I know it runs but the automatic settings didn't pick the right values.  I
just don't know where to start tinkering.  I still need to read the X config
docs so I have some idea what all those settings are in the config files.
