I am using Ubuntu 12.04 with Saucy HWE and Nvidia 331.20 with GeForce 310. I have two identical 1440x900 displays. Nearly each time I resume from suspend, I have to detect displays to get my 2nd display to come back. Sometimes I have to press the button several times and sometimes I get unknown display for the second display and the resolution is at 640x480 until I press detect displays a few more times.
The primary display is connected with dual link DVI, and the second display is connect with single link DVI adapter to display port on the graphics card.
Is this normal, or does anyone have any suggestions?
