I think I've hit basically the same problem Oleksij is reporting (blank eDP) when using the ASUS UX31E with an external HDMI monitor and leaving it plugged in while booting (https://bugzilla.redhat.com/show_bug.cgi?id=844985).
Aside from the fact Oleksij uses VGA and I use HDMI, it otherwise seems to be the same issue. I ended up finding this bug report because one of the patches attached to this bug while searching for the "bad panel power sequencing delays, disabling panel" error message I found in dmesg. I'm also still seeing the problem Bryce described way back in the original bug report: if I use Fn+F8 to disable the internal LCD, it doesn't come back unless I do a mode change on the internal monitor. That seems to be a very different problem though, as in that case eDP1 still shows up in the xrandr output. -- 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/946311 Title: only external screen is working with asus zenbook ux31e [eDP1] To manage notifications about this bug go to: https://bugs.launchpad.net/xserver-xorg-video-intel/+bug/946311/+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
