Public bug reported: Video of the problems: https://youtu.be/T9g86OZl4DU
In the video, you'll see: 1) I un-check "Require my password when waking from suspend" in "Brightness & Lock" settings 2) Suspend/Resume works fine 3) I check "Require my password when waking from suspend" and Suspend again 4) Waking up from suspend gives me a white screen 5) Clicking in the upper left reveals that I am at the lock screen (I can see the reduced set of indicators) 6) Selecting "Switch accounts" takes me to a functional lock screen 7) I suspend again 8) Upon resuming to a white screen, I enter my password blindly, and am able to unlock successfully 9) I lock my computer (lock screen is a bit glitchy) 10) I suspend from the lock screen 11) I resume, and am at the (slightly glitched) lockscreen 12) Entering my password unlocks the screen Note that the visual glitches (whitescreen, broken password prompt) aren't always the same, however, the problem reproduces in the same way regardless. For example, sometimes, rather than a white screen, I see a partial version of my desktop. Clicking the indicators, however, reveals that I am actually at the lock screen, and the same processes of typing blindly or switching accounts work fine. For easy reference, I am running a fully up-to-date version of Ubuntu 15.10. If it's relevant, I am using the open source nvidia drivers (have not yet tried this with the proprietary drivers).
