Triple fail.

[denny]

Since installing Ubuntu 9.04 I've been unable to get my three-screen set-up working again.

I can get it to run either the two screens from the PCIe card, or the single screen on the PCI card, but not all three screens at once.


Here is the xorg.conf for all three screens, and the diffs to get the two/one screen set-ups (I just remove the unwanted screens from the server layout section - everything else stays the same):

Here is the Xorg.0.log for each of the set-ups:

http://pastebin.com/m7af1b62c (2 screens, PCIe card, works)
http://pastebin.com/m177b81ab (1 screen, PCI card, works)
http://pastebin.com/m721a574c (3 screens, both cards - broken)


If anybody has any great ideas on how to fix it, I'd love to hear them.

Holy shit, really? Fuckers!

I don't think my PCIe bus is fast enough to run a quad-port card, it's one of the oldest motherboards to have PCIe at all. Also I can't get the second mortgage required to buy a quad-port card. Shit!

Two screens (two servers) with two cards works for me, though the cards are the same (nv 6600 like you).

The xorg bug seems to suggest that sometimes things will be ok with identical hardware so a cheaper option may be to add a second hand 6600 - unless the limitation is just related to a single server.

Meanwhile I also found this on LP:
