Public bug reported:
Using Ubuntu 14.10 on a Lenovo Yoga 2, when I resume the laptop from
suspend I frequently (around 50% of the time) get a blank black screen
with a mouse cursor on it, and am unable to login or interact with the
desktop at all. Often (also about 50% of the time) switching over to a
text terminal and killing "unity-panel-service --lockscreen-mode" causes
it to snap out of it and prompt me with the unlock dialog when I switch
back to X.
