http://bugzilla.suse.com/show_bug.cgi?id=798308 http://bugzilla.suse.com/show_bug.cgi?id=798308#c12 --- Comment #12 from Egbert Eich <eich@suse.com> --- Maybe to word Alex' question a little more for a non-developer: The monitor that doesn't light up is an external one connected thru DP. Now the external monitor has different power states, the 'on' state is usually signalled by a green light. Any suspended state is signalled by an amber light. Also, when the display comes on, the backlight needs to come on. Even with a fully black screen you usually see the backlight - especially when the ambient light is dimmed. Koenraad, - can you check which color the monitor power light has when the monitor is expected to be on? - can you check if the backlight is on (although the screen appears to be blank)? - In this state, please run 'xrandr --verbose' and attach the output.
