sddm hangs at random

[Caleb Howland (Menzador)]

In Kubuntu Vivid Development Branch (and in the 14.10 PPA, mark as indicated), the display manager (SimpleDesktop Display Manager) tends to hang at seemingly random times. The screen freezes, and input ceases to function. The only way to get a graphical display running properly from this point is to restart SDDM with the command [ sudo service sddm restart ].
