Comment # 14 on bug 798308 from Egbert Eich

Please don't focus "Systemsettings/Display & monitor", this is desktop specific
and may be wrong. If the problem is there the ticket needs to be reassigned to
the respective desktop maintainer, neither Alex nor me can help you.
Let's focus on what we can gather from and set with xrandr.

- What's the color of the LED when the VGA is on and shows a picture?
- Yes, please also provide the 'xrandr --verbose' output when both monitors are
  on.
- Any chance to get information on the state of the backlight when connected to 
  DP only? (It should be on when the LED is blue).
