View Full Version : [ubuntu] 'Second' HDMI monitor is not detected

September 6th, 2011, 02:05 PM
I have a laptop using hybrid graphics (INTEL [Corei7] and nVidia [GF GT550M]) and two HD externel Monitors (24" and 21,5"). Once I've conneted the 24" to the laptop and set it up everything worked fine, I had both screens enabled. Now I' ve tried to connect my second 21,5" to the laptop but it is not detected correctly. Ubuntu recognizes that there is an externel monitor but configuration/name of the Display is the one of the 24" and the connected 21,5" monitor tells me HDMI power saving mode. Under /etc/X11 I find an xorg.nvidia.conf containing a configuration for the 24" monitor.

To sum up two monitors, one works fine, the other one recives no signal but nevertheless Ubuntu expands the desktop.
