In Displays menu item I have two point: Built-in display and Unknown Display. I set built-in display to 1366x768 (primary option) and turned off unknown display. Then I suspend my laptop. And after suspend my build-in display changes to mirror option and resolution is 1024x768 and unknown display is also a mirror with 1024x768. I'm puzzled about the reason. Any idea?
