Hi.
More than one month ago I asked in this list about an issue with
my current setup that does not allow me to use my second PCI
video card [1]. While it happens with an Intel D945GTP [2], I don't think
this is specific to the main board as some say (I'm not sure).
Anyway, the BIOS doesn't show a V_BIOS for the secondary video
card.
[1] http://lists.debian.org/debian-user/2007/04/msg01227.html
[2] http://www.intel.com/products/motherboard/D945GTP/index.htm
I use Debian sid.
lspci -v | grep -i vga
01:00.0 VGA compatible controller: nVidia Corporation NV44 [GeForce
6200 LE] (rev a1) (prog-if 00 [VGA])
05:01.0 VGA compatible controller: nVidia Corporation NV18 [GeForce4
MX 440 AGP 8x] (rev a4) (prog-if 00 [VGA])
Subsystem: eVga.com. Corp. Unknown device b089
I see 4 ways out, and 2 of them are viable for me now. I'd like to know
if you had come into similar issues before and what I should try now.
I placed the questions at the end of this email.
*** 1) Get a better motherboard or Get a dual output video card
I wouldn't like to do this one. If the other options involve more than
a few hours I guess it will be cheaper for me to get a dual-output
video card. I'd prefer to fix the problem since I'd have to wait sometime
before getting the new video card and I'd have 2 spare video
cards around.
*** 2) Downgrade to xorg 7.0 since this setup was working before
I would not like to to this, but it's an option. My dual setup worked
out of the box in a previous xorg version. I wonder how I could use
an older xorg in Debian sid.
*** 3) Apply the patches that allow me to load video ROM from
a file [3].
https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=227851#c7
I tried to compile xorg with this patch, but the xorg version in sid was
very different. I tried to integrate the patch by hand but it wouldn't be
easy since some functions have gone somewhere else in the xorg tree.
It seems this patch would work around my problem since it worked for
someone else, here is what he got. Check the second line.
(II) RADEON(1): initializing int10
(**) RADEON(1): Option "BiosLocation" "file:/root/r9200.bios"
(II) RADEON(1): Read 52 kB V_BIOS from file:/root/r9200.bios
(--) RADEON(1): Chipset: "ATI Radeon 9250 5960 (AGP)" (ChipID = 0x5960)
(--) RADEON(1): Linear framebuffer at 0x58000000
(--) RADEON(1): BIOS at 0xfffe0000
(II) RADEON(1): PCI card detected
https://bugzilla.redhat.com/bugzilla/attachment.cgi?id=148129
*** 4) Do the int10 initialization myself with another program
(or another kind of initialization).
http://lists.freedesktop.org/archives/xorg/2005-July/008649.html
Well, this is new to me. It seems I cat get to initialize the card
using another method that doesn't use the Legacy VGA code
(http://jonsmirl.googlepages.com/graphics.html).
***
Now the questions:
* Is there any support in the Linux Kernel that I could use to
initialize/use the second video card? fbdev?
* What would you try if you wanted to get the second video card started?
Shall I file a bug? Xorg should take care of this. I have used more
than one video card with previous versions, with the same hardware
I have now.
* What mailing list should I try for this issue? (If it's too specific
for debian-user).
Thanks,
Nelson.-
