My setup looks like this:
- Lenovo X1 2015
- Two external screens attached
- Running Ubuntu 15.04
What I want: Close the laptop lid and mirror both screens, so not extending them but let them display the same content.
What happens now: When I click "mirror" in the display settings, the internal display and one external gets mirrored, and the second external display stays black.
Who can help? What do I have to do to mirror two external monitors?

Ok, I found the answer myself. Here are the steps:
- Open the notebook lid
- Attach the external two screens
- Go to the Display settings in the System Settings
- Deactivate the internal screen (but leave it physically open)
- install
xandr(sudo apt-get install xandr) - Go to the terminal and list all the available monitors. Therefore, just execute
xandr Now execute following command and replace the output-type with yours:
xrandr --output DP2-1 --same-as DP2-2
The last command, xrandr --same-as will let you mirror whatever monitors you wish.
