SubjectGGI and X. [was: Re: SVGA kernel chipset drivers.]

GGI is rather a "generic videocard" interface, to be put between X and the
hardware, SVGAlib and the hardware, SVGATextMode and the hardware, and
syncronizing the (already existing) VC switching process between these
components.

Since the now working code uses kernel traps for some of the interface
components (and shared libraries for other components), it's very
important to plan the X support well. I'm not talking for the GGI people,
but IMHO this is the most important task, and if this fails, then the
whole concept fails. X shouldnt suffer from such an interface! It should
run on the same speed, but with a slightly more reusable "graphics card
device driver" notion.

If X, as a way to interface with human eyes is considered to be superior,
i'd like to object. Text screens at least are and will be very useful, and
X says nothing about text screens.

[ i'm telling this as a proud owner of an SVGATextMode driven 90 Hz 100x37
16x9 charset text mode ]

It might happen that the new (and very promising) DirectVideo()
implementation in XFree86 swallows all SVGAlib applications [it should!],
but text mode is still a cheap and efficient way of doing screen based
work.

this is really a matter of taste, and i'm willing to give up textmode
once i see a nearly as usable solution in X. [yes i have a very fast
videocard]. Maybe you are right and this is only a matter of time.
