I guess you could say that. It gets the job done.

I agree that the directvideo stuff will be a real shot in the arm
for X, but to say that it will 'get merged into X' is a bit off the
mark. One of the main advantages of SVGAlib is that is *isn't* X - it
allows you to use graphics without using X, which a lot of us like.

This is also true. *Real* textmodes are, however A) fast, and B)
a LOT more memory-efficient. This is the point of SVGATextMode - you can
do a lot of playing around with it, but in the end you are still in a
textmode, not using graphics. Each has its place.

Well, I guess if we don't care about doing things in a cleaner
way, you are right. I'll be the first to admit that, right now, X is a
good enough solution for most people. Does that mean we shouldn't even
entertain the notion that things could be done better? Sure, it isn't
going to kill anyone if things continue the way they are, but why sit on
that forever? Isn't Linux all about continual advancement?

Textmode stuff is nice if it does what you need, which in a LOT
of cases it does. I grep up with an Amiga, and while the lack of
text-only modes wasn't a very big deal (actually it simplified a lot of
things), there *were* times when I could have used being able to open a
text-only screen and have it take 8K instead of 150K (640x480x16).

Thank you.
