no config

This config works.  Monitor 1 on DVI, Monitor 2 on HDMI, TV not hooked up, HD3450 only active with the 7000 inactive.

Does changing the primary vga card in the bios help?

I tried that.  Setting it to PCI first allows X to come up on just the 7000 but has no effect on getting both cards to work.

From #radeon last night:

<NoVid> Oddly changing the BIOS to "PCI is primary" came close.  I could see the logon wallpaper on the HD driven monitors but it was messed up.  Still much closer.
<NoVid> The other thing that showed is the 7000 itself works fine - it booted with that as primary and the monitor was fine all the way into initial X.

Can you attach the xorg logs and configs from when you tried the 7000 as the primary?

Also dmesg output please.

PCI primary, only PCI monitor - this works.

Only using the 7000 (PCI is primary) and no config file.  This results in one live monitor on VGA.

dmesg

dmesg as requested.

Using X -configure with the PCI as primary gave the following error:

[519.155447] radeon 0000:05:00.0 Invalid ROM Contents
[EE] Radeon(1) Cannot read V_BIOS(3) Input/Output error.

Starting X with no config results in a working X on VGA on the 7000 with the 3450 not being used.

One other thing that might be helpful.  With PCI as primary, and those Fedora RHGB and Quiet kernel things off, the machine boots on the 7000's VGA.  When some type of DRM is loaded text appears on both monitors connected to the 3450.  That DRM text survives after X loads on the 7000.  So, in some kind of text mode, all 3 monitors have text on them.

The text on the 3450 is due to the console being started on first fb device enumerated when the drm loads.  That's a good sign.  If you get a console on the 3450 and X on the 7000, then both cards are initialized properly, so appears to be a X configuration issue.  A few things to try:
1. try removing the Modes and Viewport lines from your screen sections.
2. try disabling acceleration:
Option "NoAccel" "true"
in the device sections of your xorg.conf
3. try disabling xinerama in your xorg.conf and start X with just two device and screen sections; one for each card with busids and remove the ZaphodHeads options.  You should get two X screens.  Something like:

Section "ServerLayout"
	Identifier     "Two cards"
	Screen      0  "Screen0" 0 0
	Screen      1  "Screen1" RightOf "Screen0"
EndSection

Section "Device"
	Identifier  "Card0"
	Driver      "radeon"
	BusID       "PCI:5:0:0"
EndSection

Section "Device"
	Identifier  "Card1"
	Driver      "radeon"
	BusID       "PCI:1:0:0"
EndSection

Section "Screen"
	Identifier "Screen0"
	Device     "Card0"
        SubSection "Display"
		Depth     24
	EndSubSection
EndSection


Section "Screen"
	Identifier "Screen1"
	Device     "Card1"
        SubSection "Display"
		Depth     24
	EndSubSection
EndSection

1. try removing the Modes and Viewport lines from your screen sections.

Removed, 3450 monitors no longer blank - just horizontal lines.

2. try disabling acceleration:
Option "NoAccel" "true"
in the device sections of your xorg.conf

No effect.

3. try disabling xinerama in your xorg.conf and start X with just two device
and screen sections; one for each card with busids and remove the ZaphodHeads
options.  You should get two X screens.  Something like:

Tried with and that your example with "NoAccel" added.  Blank screens.

log for 3450 with VGA.  Goes with previous attachment.


Figured I'd get back to basics.  I removed the HDMI and DVI from the 3450.  Then plugged in a vanilla VGA cable.  So, hardware:
7000 (PCI) is primary.  1 VGA connector to monitor.
3470 (PCIE) is secondary.  1 VGA connector to other monitor.

Started X with the sections for the 7000 removed.  Attachment 43907 [details] is config.  Attached is log.  No useful X.

Ok, let's close this.  It's just not worth anyone spending time on - the 7000 is just old.  No, I'm not saying that out of frustration.  I can get two monitors to work on the 7000 so that card works fine - the two cards just don't get along.  Video cards made during the stone age should probably rest in peace.  I have a second computer with a HD4??? and that one doesn't need dual monitors so I'll use the HDMI on that one for the TV.  Different room but I have legs.

Thanks for trying Alex.  I'd close this myself but the three options I get are "resolved," "assigned," and "new."  No "closed" or "pointless" option.

Thank you again for your time.

I guess invalid?
