XOrg + dual monitors = hardlock!

Hi,

I've been having this problem since 6.8.0-r1, and since I didn't find any help in the forums, I've been patiently waiting for a bugfix or something, and now i'm on 6.8.1.901 and still nothing, so I turn back to the forums for another try.

Basically, I've got two video cards, and AGP ATI All-in-Wonder Radeon and a PCI Radeon 7000. I'd been happily running X on both cards, unfortunately without direct rendering working, up from xfree 4.3 to xorg 6.7. xorg 6.8 and later, however, grind my computer to a halt if I attempt to start up using both monitors. (Everything's locked up, can't even ping the machine or light the keyboard leds) The one bright spot is that direct rendering is working now, but I can only use one card at a time. :cry:

(both work individually)

Anybody have any ideas?

Thanks,
Ricky

If it helps, my xorg.conf:

and my emerge info:

when does your PC lock up? when you're booting linux, or when your're starting x? for diagnostic purposes, you may want to config your PC so that X doesn't load automatically. this might make it easier to determine when the lockup is occurring.

I guess I should have been more specific. I log into the console and run X via startx. X begins loading, and once both monitors have been initialized, the both get stuck on black. I can't access logs or such at the time, cuz everything is frozen.

are you attempting to load a window manager, like kde or gnome, or are you just loading the ugly little x window manager, twm?

do you see any sort of cursor when the screens go blank, or nothing at all?

kadaver_: I tried your suggestion, and I don't lock up when I try my default layout, but I only get one monitor now, so it's kinda the same thing ;-)

I get the following in my xorg log:

hmm... anybody have any more suggestions?

I'm all out of suggestions. Although I might have one more =)

You have three monitors right?
Have you tried going dualscreen with only two (one on each card)?
If that works you can begin troubleshooting from there.

Actually, I only have one on each card. The 0 0, i think, is to set the origin at the top right of the screen 1. I got it from some other config, but perhaps it's only applicable to xinerama.

For what it's worth 6.8.1.902 doesn't seem to make any difference. Also, if anyone sees anything useful, here's as much of the xorg log as actually gets written:

So, I've been toying around with stuff, and apparently if I disable DRI, it works. (I seem to recall trying that before and it not working, so I guess something got fixed along the way. ;-)

)

This is kind of a less than ideal solution, for obvious reasons. (glxgears drops about 800 fps

) So, now that we know that DRI is the problem, does anyone know of any possible fixes? Or at least a bug report or something I could watch?

Thanks.
