Here's the drm.debug=6 dmesg output for the xorg.conf configuration I've pasted above (UXA).
I can confirm that this is a bug in xserver-xorg-video- intel_2.21.5-0ubuntu1. I downgraded to xserver-xorg-video- intel_2.20.9-0ubuntu2 and the issues went away. ** Attachment added: "uxa.dmesg" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1161112/+attachment/3601850/+files/uxa.dmesg ** Changed in: xserver-xorg-video-intel (Ubuntu) Status: Incomplete => New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1161112 Title: Raring regression: SNA fails completely; UXA causes random hangs To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1161112/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
