3 Displays with 2 ATI PciX Grafic-Cards

Hi,
I have three TFT-Displays and want to use them with Open-Suse 11.1.

There are two ATI HD4760 PciX Cards in an AMD 790X-Mainboard (MSI K9A).

Two Displays on first card in Dual-Head is working (done via Yast2). But I can’t get the 3rd Display on 2.Card get working. Yast2 doesn’t show more than 2 displays. So I tried many things in the xorg.conf, but none worked. Driver is ‘radeonhd’.

Booting WinXP all three display are working like a charm, so there should be no hardware-problem.

lspci and hwinfo --gfxcard deliver two BusID’s (1:00:00 an 2:00:00). Are these the two gfxcards ore are these the two outputs of the first gfxcard?
→ edit: Ok, I have checked this by unplugging the 2.card, well: the two bus-id’s are two gfxcard’s!

Has anyone an idea?
Any help is welcomed…

thx in advance,
kddh

Hi,
Sorry, but for some Reason I can’t edit my own Posting, so I have to reply… well, some (further) things to know:

  1. I had a twister in the posting before, the gfx-card is a ATI Radeon HD4670.

  2. If I edit the xorg.conf and only change the BusID in the Device-Section, I get the output on the third screen (=second card). The first two displays therefore stay dark.

The forum limits to 15000 Chars per posting, so I have to split this one…

Here is my xorg.conf, part1:
