Public bug reported:

Every time I resume from suspend, my display is garbled (looks a bit
like the loading screen from a Commodore 64). A "sudo service lightdm
restart" from a different console (Ctrl+Alt+F1) fixes the issue, but
logs me out of the session as well. I get past the login screen, and
sometimes the display is fine for about a minute or so, but it
inevitably garbles up. The artifacts shift when I move my mouse, and
will occasionally have a clear picture for a frame or two, or if my
mouse is in a specific point, and not moving. This error was not present
before I upgraded my system from an AMD RadeonHD 6870 to an Nvidia
GeForce GTX 1060, and I therefore believe this is a bug in the nvidia
drivers, rather than lightdm itself.
