Hi Bryce, I'm attaching the dmesg with the experimental kernel :
Linux ubuntu 2.6.39-994-generic #201104200727 SMP Wed Apr 20 07:52:44 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux I did a full amd64 install, installed this kernel, booted with it, plugged in the external monitor, and pressed the hotkey a few times. Display flickers as usual, but the external display shows nothing, even insisting that "vga cable has no signal". Thanks! ** Attachment added: "dmesg-next.txt" https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/754799/+attachment/2080247/+files/dmesg-next.txt -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/754799 Title: [arrandale] external VGA output doesn't output anything (i686) -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
