Thread: cannot set up dual monitors in ubuntu 12.04


after upgraded 12.04 dual monitors stopped work. after try set id settings/display error:

selected configuration displays not applied: required virtual size not fit available size: requested=(3840, 1080), minimum=(320, 200), maximum=(1920, 1920)

failed apply configuration: %s gdbus.errorrg.gtk.gdbus.unmappedgerror.quark._gnome_2drr_2der ror_2dquark.code3: required virtual size not fit available size: requested=(3840, 1080), minimum=(320, 200), maximum=(1920, 1920)

if try edit in amd catalyst control center (i run command gksu amdcccle) this:

(process:2955): glib-critical **: g_once_init_leave: assertion `result != 0' failed

(process:2955): glib-gobject-critical **: /build/buildd/glib2.0-2.32.3/./gobject/gtype.c:2722: forgot call g_type_init()

(process:2955): glib-gobject-critical **: g_object_new: assertion `g_type_is_object (object_type)' failed

tried restore xorg.conf many times , start on did not help. have ati radeon hd 3450 video card , ati/amd proprietary fglrx driver installed.
