This problem seems to occur every time I undock my laptop and then when it goes
into suspend mode.  Upon trying to access the system again by hitting the power
button all I get is a black screen and a mouse cursor.  I can access a virtual
console and restart the machine, but there doesn't seem to be any other way to
recover at this point.  I'm not sure if this is a kernel issue or a desktop
issues.  I tried looking at the logs when this happens via journalctl but I
didn't see anything of significance logged.

This is happening with Leap 42.2 RC2.  The hardware is a dell latitude E7440.
