[Bug 1300914] Re: External screen undetected after first plug
You're right Peter: logging out to lightdm also works for me.
However quitting the GUI session is the real pain for me: it's very
often that I have two dozen windows spread over a few virtual screens,
everything arranged in just the right order. I just hate loosing this.
Rebooting only adds a few seconds after the SSD upgrade but I would
gladly wait a couple of minutes if I could save my GUI session.

Title:
External screen undetected after first plug
Status in linux package in Ubuntu:
Confirmed
Bug description:
On Ubuntu 14.04, the external screen plugged on VGA is detected and get activated correctly.
However, if I unplug it and then replug it later, it is not detected anymore and the screen receives no signal.
A way to get it back to work is to reboot or simply suspend the
computer.
Sorry but I have no idea of what package is handling that.
