My computer at work has been upgraded to a system with an integrated i915=20
graphics card. Although I can make Xorg work with the i810 driver, I am=20
having some issues. First off, the system is an HP dc7100, which has no=20
AGP, just PCI express, but Xorg wants to treat it like it is AGP. Apparent=
ly=20
this is causing video memory to be limited to 8MB. This causes a variety o=
f=20
other things to fail, such as DRI. I am running 6.8.1 on FreeBSD 6-CURRENT=
=2E =20
Here is the relevent section from my xorg.conf file:
Section "Device"
#ChipSet "RV280"
Identifier "Intel POS"
Driver "i810"
#Card "vga generic"
VendorName "Intel"
BoardName "Intel POS"
#ChipId 0x514D
#Option "EnablePageFlip" "on"
#Option "AGPMode" "4"
#Option "AGPFastWrite" "yes"
#BusID "PCI:1:0:0"
VideoRam 131072
Option "BusType" "PCIE"
EndSection
It contains some cruft from my old ATI AGP card, but that has largely been=
=20
commented out. The "BusType" Option was a test, which doesn't work, of=20
course. Here is what my log file shows:
(II) I810(0): detected 7932 kB stolen memory.

If the full config file and log are necessary I can attach those to another=
=20
email. Note, I am assuming this is a Xorg issue and not a FreeBSD issue, bu=
t=20
I have no real, but I am copying the FreeBSD X11 list on this email because=
=20
of how pciconf reports the onboard card:
none0@pci0:2:0: class=3D0x030000 card=3D0x3005103c chip=3D0x25828086 rev=3D=
0x04=20
hdr=3D0x00
vendor =3D 'Intel Corporation'
device =3D '82915G Graphics device'
class =3D display
subclass =3D VGA
I'm not sure why it would report the device as none0@, nor do I have any cl=
ue=20
as to whether this is why X is trying to probe the device as AGP, since the=
re=20
is no agp device in the system. However, I do still have agp support in my=
=20
kernel. Is there anything I can do to prevent X from trying to attach to a=
=20
nonexistant agp device?
I apologize for the cross-post, I do it only because of my uncertainty as t=
o=20
where the problem lies. Thank you for any help you can give.
PS: If there is a way to search the xorg list, I can't find it, can anyone=
=20
enlighten me on that one?
