after Upgrade from 12.04 to 12.10 I can't work with dual monitors. The desktop is freezing after a short while when I attache the second Monitor. I can use the touchpad, but the desktop isn't reacting anymore. Sometimes I can switch with Ctr-Alt-F1 to terminal-mode, but i can't restart lightdm or something else, just reboot. 12.04 was working perfectly with two monitors. The only error-message I found in syslog:
gnome-session: Gdk-WARNING: gnome-session: Fatal IO error 11 (Die Ressource ist zur Zeit nicht verfÃ¼gbar (The resource is not available)) on X server :0.#012
I don't know if it concern to this problem.
My Hardware: Asus eee pc x101h with intel gma 3150 on atom n570.
The desktop is Unity
It would by nice, if someone can help me.
Upgrade: I installed the gnome-shell and tried out if the problem occurred too and until now it doesn't. So it is only a unity problem.
