Description need.coffee 2008-11-13 11:32:31 UTC
Trying to setup dual head with two Quadro FX 3500 cards,
one monitor on each cards' CRTC 0.

The first card initializes fine and shows:

(--) NV(0): VideoRAM: 262144 kBytes

The second FX 3500 card does not, showing:

(--) NV(1): VideoRAM: 0 kBytes

Of course, it won't accept any modes.  I've tried 
several configuration variations and it is always 
the same.  It is still the case in nv-2.1.12.

Additional errors:

[...]
(II) Reloading /usr/X11R6/lib/modules//libint10.so
(II) NV(1): Initializing int10
(WW) NV(1): remove MTRR a0000 - c0000
(==) NV(1): Write-combining range (0xa0000,0x20000) was already clear
(EE) Cannot find empty range to map base to
(EE) NV(1): Cannot read V_BIOS (3)
[...]

I've read that one head per gpu should work with nv, so I
am hopeful this can be resolved... thanks in advance.

I have a similar problem. 2MiB of memory are detected instead of the correct value of 128MiB when my FX5500 (PCI card) is not the primary VGA in BIOS. Trying to specify VideoRam in xorg.conf is not helping.
Versions: xorg-server 1.5.3, xorg-server-utils 7.4, xf86-video-nv 2.1.12.

I don't know about 2 MB, but having it report 0 MB is typical of the GPU not being POSTed by the int10 module.  The int10 module is part of the xfree86 DDX, so reassigning to DDX/xorg.

Nouveau doesn't have this problem.
