Video Card support etc., without X
by Samawi on Thursday 07/Dec/2000, @08:05

How would KDE support video cards without X. Is there a way of just using those parts of X that pertain to video cards? What about the new anti-aliasing features?

Can KDE really just canniblize X to create a lean, mean, Windows-eating machine?

If any of the developers could give the brodest outline of what it would take to create KDE-NOX, that would be great to read!

I wonder if it would be possible to just use the video card drivers from Xfree 4. Since they are now nice and separate from the server I would think that would be possible. Of course you could only run KDE apps, but I think it would be really nice for trying to create a low-overhead GUI for things like kiosks and what not.

Not really. You see, KDE wouldn't be making their own personal version of display drivers, rather, it would be using the internal framebuffer drivers that are loaded as part of the kernel. I'm not certain if FBDEV yet supports acceleration, but it runs in SVGA mode just fine.

the new kernel has its own accellerated drivers for a number of chipsets as well as a perfectly useful frame buffer. there ought to be some way to use kde right on top of the kernel -- which is, after all, already in a graphics mode.

anybody know what modifications would be needed to bring this about?

I haven't worked on KDE development much so don't know about the kdelibs and other libraries in KDE and there dependency on X.

However yestarday I was looking into qt/embedded(qte), based on my preliminary analysis there is a kernel directory within qte/src, the qgfx*.* files should give anyone a rough idea of how qte provides a flexible graphics layer.

Roughly:
1) One could use the Framebuffer driver in Linux kernel for their target to work with qte because qte already as support for Linux framebuffer.

OR

2) One could implement ones own graphic drivers by inheriting from qScreen for the framebuffer part and from qGfxRaster for the Drawing primitives.
