lightdm

When is loading and two monitors are connected, instead of a login screen I see this: enter image description here

...after clicking OK, selection appears: enter image description here

Then I'm following to console login, disconnecting by hand the secondary monitor cable, restart lightdm with a command

sudo service lightdm restart

...and voila! System loads fine. If I disconnect the cable before boot X will be loaded fine too.

It's not a nice 'feature' when I have to disconnect the cable each boot or X restart.

I was trying to delete monitors.xml but it didn't help.

The situation relates to my notebook with Intel integrated GPU. The same happens on two different pairs of monitors: at the office and at home.

How can I fix this?

Ubuntu 12.04 x64 Desktop with default Unity GUI.
