OK, so attached is the result of a two-reboot cycle. Initially (first reboot) I didn't have the monitor attached at all.
Then I ran your diagnostic scripts (output in post-reboot-unattached). Then I attached the monitor. Then I ran your diagnostic scripts (output in post-reboot-attached- after). Throughout this process, no signal was received by the monitor, even though the Gnome randr GUI detects the correct manufacturer, shows that the monitor is on, and indicates that it is using the correct resolution. I finally rebooted the laptop WITH THE MONITOR ATTACHED DURING the reboot and that was the only way it successfully started sending a signal. I then ran the diagnostic scripts for a third time (output in post- reboot-attached-during). I have not bothered to work with a suspend/resume condition, as it happens whenever the monitor is not attached on boot anyway, whether or not I suspend/resume. ** Attachment added: "Script I ran, and series of three conditions in separate directories." https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1218224/+attachment/3799362/+files/xrandr_debug.tar.gz -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1218224 Title: VGA Output not activated To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xserver-xorg-video-intel/+bug/1218224/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
