Bug Description
I have a small PC running Xubuntu using my TV as a single/main display. Since upgrading the box to 16.04 when i turn off the TV and turn it back on the screen stays black (well actually it's blue but this it what my TV does if there is no input).
xrandr tells me that the graphics driver did correctly detect the TV going away and also coming back. The screen comes back if i run:
xrandr --display :0 --output HDMI3 --mode 1920x1080
The same is happening if i unplug the HDMI cable and plug it back in (tested with my TV and another HDMI monitor).
Also if no user is logged in and lightdm is shown everything works as expected.
My theory is that the xfce settings daemon does not configure 'new' screens despite the fact that the checkbox in the xfce4-display-
Status changed to 'Confirmed' because the bug affects multiple users.
