I've a ZenBook UX32VD laptop with a Intel i7-3537U CPU. I'm on ubuntu 12.10 (kernel 3.5.0-23-generic, xorg 1:7.7, nvidia-current 304.64 and gnome-shell 3.6.1). This laptop has a nVidia card with the optimus technology.
I've three monitors that i want to connect to my laptop. The laptop screen has a resolution of 1900x1080, i've a iiyama screen with a resolution of 1920x1200 and finaly a acer screen with a resolution of 1366x768.
My goal is to have the iiyama screen as primary, the laptop on left and the acer on the right.
When i connect all the monitors, gnome-shell blinks and finaly displays a black screen (on the 3 monitors) and shows only the mouse pointer (i can drag the mouse over the 3 monitors).
When i set a resolution of 1680x1050 for the iiyama screen, all is working fine... :( If i disable the Acer screen, then i can set the max resolution on both the laptop and the iiyama screen.
I've pasted the result of the command xrandr -q on this link: http://pastebin.com/i6J6maUP eDP1 is my laptopt integrated screen, HDMI1 the iiyama screen and the acer screen is VGA1. I don't know who is the DP1 disconnected screen.
Someone knows this problem? How can i debug it? I've no error in Xorg.log, nothing in syslog or in dmesg...
I've no easy way to do the test with Windows.. (i'm working with LVM and i don't want to break the system..)
