[K12OSN] Intel D945GCLF2

Yes, we're attemping to use the onboard video.  We've already tried
those suggestions of "nomodeset" and other various settings in our
hunting, in F10, the driver was working, and Plymouth would also work,
and it seemed like Compiz was functioning to a degree at least.

However, any 3d-application would be unaccelerated, using only software
rendering.  A dump of glxinfo shows that it is using the software
renderer vs. the intel accelerated flavor, but yet a live distro CD will
run fine, with the proper acceleration.  I suspect we must be missing
something in the boot image or configuration that is causing this to
occur, but am unsure of what to try next.  All of the proper libraries
appear to be in place.

Are you talking about the onboard graphics card. 

If so there is a problem with the current driver. (As a side note this
problem has also been reported with windows so it known problem on
intels side). See my bug report here.



1. Do you see the plymouth boot screen? if yes then it is using the
intel driver. I would recommend using F10 version. The driver works but
has problems with compiz. And you have to adjust grub if you want to see
the plymouth boot screen (vga=792 nomodeset)

If no, then it is prob using vesa like you said but I think not. Try
recreating the X11 config file and force it that way.

1. Install system-config-display
yum install system-config-display

2. Run system-config-display and save your changes. This will create
X11.conf file and will use this config when boot your server.

3. Also try using 'nomodeset' in grub (tell me if you need help on how
to do that.

I hope this helps
