Adam,
It looks like you've developed a wealth of information about how video works
on Linux in general and on YDL in particular.
The major elements that play a role in Linux video while you are viewing a
screen in X as I understand them are:
The monitor hardware and its hardware modes, settings and adjustments
The video card, its settings and its memory
The video driver program and its modes and settings
The X window system, the X display and its settings.
fbset
X applications
Pam
The Linux console
The Linux kernel
Where does the framebuffer fit in? What else is missing.
I think getting X to work the way you want it to is a bit like coaching a
ball game. You have to get the right combination of players on the field.
You've got a whole roster to choose from: Various XFree86 versions, several
drivers, many video cards and monitors. Its quite a diverse team.
So what players do we have to choose from and once chosen how do we set them
up? Who's on first?
Is there a single document that ties all this stuff together in a general way?
-Pat
P.S.
This topic is very complex and interesting. I think a diagram would help me
understand this better.
Here's an e-mail that just came in yesterday about a diagramming program.

Sketch 0.6.11 - A vector drawing program
Sketch is a vector drawing program for Linux and other unices. It's
intended to be a flexible and powerful tool for illustrations, diagrams
and other purposes.
It has advanced features like gradients, text along a path and clip
masks and is fully scriptable due to its implementation in a combination
of Python and C.
More information, sources and binaries are available at the website:
