[Mesa-users] Frame buffer object extension (FBO) support for Intel 945 graphic core

Hello all,
We have a linux box with Intel N270 processor (with 945 graphic core
inside). Our Linux supplier downloaded and installed libGLgn3.so from Intel
IEGD package. However, this openGL library from IEGD does not seem to
support frame buffer object (FBO) extension, as no related string output
from glxinfo is found.
Besides IEGD library, there seems to have another way to include Intel linux
graphic driver (xf86-video-intel+mesa3d):
http://intellinuxgraphics.org/
What's the difference between two Intel graphic driver approaches?
a. Intel IEGD openGL
b. Intel linux graphic driver (xf86-video-intel for 2D rendering and
Mesa3d for 3D rendering)
and can I use either approach for hardware-acceleratation of 945 graphic
core?
A separate question:
With software rendering of mesa3d (./configure --with-driver=xlib), I
have FBO extension available. Occasionally the background of frame buffer
object is cleared to a different color than what I specified via
glClearColor(red,green,blue,alpha). It occurs very rarely and I can not
reproduce it on demand. Any way to debug framebuffer object drawing?
Thanks in advance.
