[Desktop-packages] [Bug 1463926]
If the hardware issues a hotplug irq when the cable is still connected, there's not much the driver can do, really. We check the link on hotplug, it's still there, do nothing. The HDMI live status checks that have been merged *might* help a bit, but otherwise, I'm closing as WONTFIX. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to xserver-xorg-video-intel in Ubuntu. https://bugs.launchpad.net/bugs/1463926 Title: Removing HDMI cable will not always resize the desktop Status in X.Org X server: Won't Fix Status in xserver-xorg-video-intel package in Ubuntu: Triaged Bug description: Plugging in an HDMI cable in my laptop will automatically cause Unity to resize the desktop to span both screens.

Only the manual probe sees the monitor as disconnected, triggering a round of userspace notifications and retraining. Use xrandr --current to avoid the manual probe.
