12.04 and just hit this now when plugging in my Vizio TV in via HD. Cleared out my monitor.xml to get around it. When I plug in, my laptop monitor always goes black then both screens turn on. Sounds like it's something where the monitor configuration util is not getting the 'turning them back on' part when it loads the config. Probably stalling to show some message or something but since you have no display at the time you never see it.
If anyone can recommend some logs to gather or what I ought to attach a gdb to if I can repro the issue,please let me know. I have a backup of my bad monitor.xml. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/926637 Title: Xorg crashes to black screen when attaching HDMI Samsung monitor to laptop To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-nouveau/+bug/926637/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
