fglrx spins when starting X

[rjm887]

Hi,

I'm posting here hoping someone has seen a similar problem with the fglrx video driver. The box I'm trying this with has two Radeon HD7970 cards installed. With only one, I can get an X desktop. When I install the second one, X reaches 100% cpu when I try to start it. I'm at a loss as to what might be wrong. I'll post whatever relevant information I can in hopes that someone can point me in the right direction. Hoping it's something stupid I'm doing wrong on this end and not a driver problem. Interestingly, it did start a couple of non-consecutive times without a pattern I can identify... Is it something I did and simply can't retrace... is it coincidence? I'm not sure. I confirmed both cards work (always, not just once or twice) independent of each other, just not together. Also, once this starts, I can't seem to get control back: ctrl+F# does not give me a usable VT. The two monitors disable when I use startx or startxfce4 and I need to reboot.

[The xorg.conf below deliberately only tries to make use of one as I've been trying things for several hours and I'm trying to make my test as simple as possible.]
[This is with ati-drivers 13.1, xorg-server 1.13.4, kernel 3.9.6]

Here is the backtrace when I interrupt X with gdb (interrupted numerous times):

If you read this Archlinux thread you can see that some users there, are experiencing similar problems. Try the following;

1) emerge the latest version of the x11-drivers/ati-drivers, 13.6 beta.

2) Use the amdconfig/aticonfig utility to configure your xorg.conf for dual display adapters
