Did you get a chance to test the elderberry PPA I posted? After that, one other thing I'd like you to test before this gets forwarded upstream, please install the drm-intel-next-proposed kernel here:
http://kernel.ubuntu.com/~kernel-ppa/mainline/drm-intel-next-proposed/ Reboot, then reproduce the problem. Run 'dmesg > dmesg.txt' and attach dmesg.txt and /sys/kernel/debug/dri/0/i915_error_state to this bug report. Marten, I'd particularly like your feedback with this data, since you're the original reporter for this bug report. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/750259 Title: [arrandale] Dual screen not working/shows corruption (x86_64) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
