Make DisplayLink drivers work with suspend on Ubuntu

My DisplayLink-attached screen went awry after resuming from suspend, and I see that it's a known issue. Not being able to use suspend on a laptop is a major loss of functionality for me.

        xrandr does not help. I have tried

        sudo xrandr --auto

        and

        sudo xrandr -s 0

        to no effect. I don't see any other options in the man that appear to be useful. Is there something else you had in mind?

        The new release 1.2.58 does not work at all for me. I am running Ubuntu 16.04 on an HP G72 laptop with an AOC e1649wu USB monitor as a secondary monitor.

        I was previously running the 1.1.68 release, which worked fine except that the USB monitor would not come back on after suspend. I downloaded 1.2.58, ran sudo displaylink-installer uninstall, rebooted the computer, and installed 1.2.58

        When I boot up, the primary screen is fine and the USB monitor has alternating purple and blue(?) horizontal bars. After about 15-20 seconds the USB screen goes black. lsusb shows the DisplayLink monitor as present.
