Title: External screen on mini-DisplayPort no longer detected Status in Unity: Confirmed Status in “unity” package in Ubuntu: Confirmed Bug description: My laptop has a mini-DisplayPort and an HDMI port to which I can connect external monitors. When I plug it in into the HDMI port, it is properly recognised but when I plug it into the mini-DisplayPort, Unity fails to recognise the display. This used to work in 12.10. Steps to reproduce: 1. Plug in the external display to the HDMI port via an HDMI adapter: the Unity display extends to the second monitor 2. Plug the same display to the mini-DisplayPort adapter: the screen stay blank 3. Open System Settings -> Displays: the external monitor is no detected.
