please, give me some link i cant find anything about that?

i managed to find this tho:

There is lots of embedded X, what do you think the N800, back to the
Digital IPAQ are running?.. there is also the twin project which is
being used to do a bootloader which is an embedded windowing system...
Miniglx and EGL are the two project that are trying to do a HW
accelerated open source GL stack with out X, we don't have driver for
many cards that support these, and there is a lot of other work to be
done around card setup before this can happen. Miniglx is considered a
hack and *embedded* people use it where they know what graphics chip
they want to use...

You are talking, listening you need to do more off, it hasn't been
done, people won't just work on your project because you ask people
will work on what they want to work on and if benefits you so be

Scitech isn't the solution to anyone else's problem it may be the
solution to your problem in which case well done you've found a
solution but I don't think anyone here is going to put resources into
Scitech software which from the source I can read is sw rendered GL,
I've even downloaded it to find that out. EGL is something that will
probably be off use in the future but it will not run on all the GPUs
available each open source supported GPU driver needs to be ported to
the EGL system, and this requires major changes to the Linux kernel
and Mesa, until these changes are done you probably cannot use EGL for
your project, these changes are not being done to any timescale,
people work on them whenever they want and your project will not hurry
those ppl along..
Is that clear enough?
