I have two external monitors running on my MacBook Pro Mid-2012 running OS 10.7.4. One through the display port and the other using the display link usb adapter. The screen saver comes on randomly, while using the mouse and keyboard. The monitors are constantly powering off and on and the one attached via the USB adapter will sometimes lose a data connection and the usb cable removed and then reinserted into the MacBook port.

I tried the DisplayLink driver 1.7 and also 1.8a1. Neither works properly. I had to revert to 1.7 to get the monitor using the USB adapter to work at all.
