I have similar problem. When using dual screen setup with Intel 945, everything works as expected. gnome-display-properties shows two monitors. Now If I select "Clone Screens" checkbox screens are cloned, that is correct. But problem is that when I now deselect "Clone Screens", It does not change back to extended desktop setup. And gnome- display-properties also shows only one monitor.
Only by resetting ~/.gnome2/monitors.xml it is possible to go back to two monitors/extended desktop setup. ** Attachment added: "xorg.conf" http://launchpadlibrarian.net/15189707/xorg.conf -- gnome-display-properties only allowing cloned screens https://bugs.launchpad.net/bugs/238215 You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gnome-control-center in ubuntu. -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
