Try something like xrandr --output LVDS1 > --auto --output VGA1 --auto --right-of LVDS1 > > jsteel > xrandr output http://pastebin.com/z9G4n1Sp This is what I use to initialize the two monitors when X starts xrandr --output LVDS1 --auto --primary --output HDMI1 --auto --right-of LVDS1 And it has no effect as the monitor connected to receives no signal (it goes to sleep) Also, as I mentioned before I don't see the output during the boot either so I assume this is not an X thing. Maybe 3.5 has some modules turned off by default? or this is a bug. I couldn't diagnose it properly. Thanks. -- Sudaraka.
