Binary package hint: xorg

Dual screen over VGA is no longer working for me under Natty. It used to work fine under maverick, but since the upgrade it just shows corruption/flickering screen. Whenever I'm using one screen it is working fine, and when I plug in my second screen my main (internal laptop) screen turns itself off and the external monitor keeps flickering at high frequency, showing random colours and sometimes little pieces of background. It doesn't matter whether the monitor is plugged in at boot or not. I have reasons to believe that the intel driver or xorg causes the problems because the GRUB and the login screen work both fine on both screens at the same time. As soon as I'm logged in this behaviour shows. It also doesn't matter if I'm using classic GNOME or the Unity interface. Xorg.0.log and dmesg are not showing any errors.
