Created attachment 187784 [details] stack trace command was: Xdmx -display localhost:3.0 :5
Right, well I guess Xdmx is broken for real. Sorry. You might want to contact upstream about getting it fixed in 1.6 or in the master branch. I don't think any of us have the time resources to fix Xdmx. Thanks
Also hit this bug. If someone reported to upstream, please give a link to bug here.

Xdmx is still seriously broken in git master. There's a dmx2 branch from Novell but it hasn't been merged and it's now getting older. @Donnie, what do you say we stop shipping Xdmx? It's obviously broken and no-one upstream seems to care... Thanks

It's obviously broken and > no-one upstream seems to care... I suppose. Not sure what else people are using for display walls these days, though..
This patch fixes the segfault for me: http://cgit.freedesktop.org/xorg/xserver/commit/?id=6f1d5147cb394b7c83c4c1447c78890fa2b40a45
Looks like this patch is included in xorg-server 1.6 and newer. If you have any more issues, please don't hesitate to file new bugs. Thanks
