seat 0 config

I'm running a multiseat setup with 2 radeon (ATI3650HD and ATI5450HD) and 1 intel cpus, I'm using libdrm, mesa and xf86-video-ati from git on gentoo.

I'm syncing with the repos every thursday, yesterday I've syned with the repos and after boot today, all the screens connected to radeon are black.

in the sync last thursday everything worked ok, also when downgrading to xf86-video-ati-6.14.6, the system works.

when observing the commit logs on xf86-video-ati of this timeframe, the only commit is enabling 2D tiling.

xorg logs can be found at http://bpaste.net/show/55347/ (bad boot log) and at http://bpaste.net/show/55346/ (good boot log)

Are you sure it's the 2D tiling commit?  Does just reverting that commit fix the issue?  I think it's probably another commit.  Does your tree have:
http://cgit.freedesktop.org/xorg/driver/xf86-video-ati/commit/?id=39eac3104c2f08b4d78aab3f88fd104301eb4711
Can you try again with git master?

Hello Alex,

I'm not sure, correct me if I'm wrong but Zaphod is for running seperate x sessions on the same card?
I'm using a card per session.

anyway, I'll revert the patch and try, will report soon.

You are correct, but I'm wondering if that patch is causing a problem in your case.  You might try reverting that patch as well if the 2D tiling patch doesn't help.

Which should fix the Zaphod mode problem without breaking non-Zaphod mode. Sorry about the goof.
