Hi All- newb question here:
Running Gentoo on a 2.6.17 kernel and trying to get xorg to work. I understand this sounds like a software issue but my question revolves around my integrated video card:

lspci:
00:02.0 VGA compatible controller: Intel Corporation 82915G/GV/910GL Integrated Graphics Controller (rev 04)
00:02.1 Display controller: Intel Corporation 82915G Integrated Graphics Controller (rev 04)

My question is, why does my card take up two BusID's?? When trying to config xorg, I can only list one BusID or the other. As soon as xorg sees the second BusID, it forgets about the first one and errors out.

xorg.conf file:
Section "Device"
Identifier "Card0"
Driver "i810"
VendorName "Intel Corporation"
BoardName "82915G/GV/910GL Express Chipset Family Graphics Controller"
BusID "PCI:0:2:1"
BusID "PCI:0:2:0"
EndSection

Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
SubSection "Display"
Viewport 0 0
Depth 16
EndSubSection
EndSection

X -config error message:
(++) Using config file: "xorg.conf.new"
(WW) I810: No matching Device section for instance (BusID PCI:0:2:1) found
(EE) I810(0): unknown type(0xffffffff)=0xff
(EE) I810(0): VBE initialization failed.
(EE) Screen(s) found, but none have a usable configuration.

may be you should modprobe some more modules?
before running X up?

Can you be a bit more specific? I have the modules running for the graphics card. What else would I need?

the device 00:02.0 has a slave : 00:2.1

the slave is a sort of HW extension (dual head? TVout? ???)


I would try to delete one or the other BusID and try it...

That's a great suggestion... From what I've read, this card is capable of multiple monitor outs - one for CRT and LCD (weird). I don't need the CRT functionality, but I don't know how to disable that BusID. Do you know how to do that?

just delete that line from the config file...

I figured that... I mean, how do I disable that busID from the OS? If I just remove it from the config, I get the error:
"(WW) I810: No matching Device section for instance (BusID PCI:0:2:1) found"
-OR-
"(WW) I810: No matching Device section for instance (BusID PCI:0:2:0) found"
depending on which line I remove from the config file.

I think X meand that he has no hooks (no device-nodes in /dev/) to connect to...
Lookup /usr/src/linux*/Documentation aboyt intel's 810 family of chipsets...
find the right kernel modules and load them...
look at /usr/doc/ for intel810 too

I got the same problem, and just solved it thanks to

Solution: add vm86 support into your kernel

these warnings are nothing to worry about:

It worked perfectly!! Thanks!
