The HDMI connection works flawless when running the laptop with Windows (dual-boot) Xrandr only shows the standard monitor the full output of xrandr is xrandr: Failed to get size of gamma for output default I only want the visible screen output shown on the external monitor as well, which works fine when starting the laptop with the Windows OS (without any change to hardware and/or cables).
How can I fix this problem in order to see the current screen on both, the laptop screen and on the monitor screen?Īlso, it is unimportant if the screen can play the laptop's sound.
The HDMI cables are both plugged in to the laptop and the monitor, and the monitor is switched on.Īnd clicking on 'Detect Displays' only the standard laptop screen is shown. On a Lenovo Laptop with Ubuntu 14.04 I am not able to display the current screen's stuff on a Monitor connected with HDMI.
